When it comes to producing a sequel to a masterpiece, it's often the case you just can't do the original justice.
That was far from the case when Gennady Golovkin stepped into the ring against Saul "Canelo" Alvarez in Las Vegas for GGG vs Canelo 2.
The first fight, which took place just over a year ago had it all. A compelling bout between two of the greatest pound-for-pound fighters of their generation, it was the weird, skewed set of judges scores that was talked about in the hours and days afterwards.
Already the discussion over part II in the series will rumble for the coming days.
Alvarez won a points decision as Triple GGG lost his first ever professional fight. In the process the Kazakh fighter relinquished his WBC and WBA middleweight titles at the T-Mobile Arena. But that wasn't the whole story.
Again it was the judges scoring and the awarding of a points victory to the Mexican which has caused huge debate.
How the fight unfolded
Our boxing correspondent Gareth A Davies predicted a split-points decision to Canelo before the bout. Here's how he saw the 12 rounds that followed and his own scoring.
Round 1: GGG busier with the jab throughout. Canelo much more static than first fight. Very close. GGG 10-9
Round 2: An excellent Canelo round with body shots from the Mexican. GGG is marked under the right eye. Canelo 10-9.
Round 3: Another good round by Canelo, making GGG pay every time he misses. Canelo lands more and is busier, it is working for him being the aggressor and his hand speed is telling. Canelo 10-9
Round 4: A terrific uppercut from GGG which turns Canelo. Both are technically brilliant. Both hunting for weaknesses. Alvarez trying to walk him down and trying to counter but getting caught. There's a nick over Alvarez's left eye. GGG 10-9
Round 5: No let up in the pace. GGG nicks this round, better work all round, and there is a deepening cut on Alvarez's left eyelid. GGG 10-9
Round 6: Spearing jab from GGG then an uppercut. Big shots from Canelo, but more scoring shots from GGG again. Very close, but GGG landed more. GGG 10-9
Round 7: Canelo is more assertive again. GGG finishing strongly with a quality uppercut, but it's Canelo's round. Canelo 10-9
Round 8: GGG blowing a little. And Canelo by the end of the round. Claret running from from the left eye of Canelo down his face. An amazing fight... Canelo wipes away blood from his nose now. GGG 10-9
Round 9: Bigger cleaner shots from Canelo but quality and volume from GGG making Alvarez fall short. Quality left hook from Canelo, same from GGG. Canelo complains he was headbutted. Canelo proudly marching forward but clear fatigue in his body. Big shots that round from both. GGG 10-9
(Gareth has GGG ahead 87-84 at this point)
Round 10: Best round of the fight so far. GGG looking tired for first time but a brilliant right hand from GGG hurts Alvarez. Now Alvarez attacks. GGG breathing HARD. All about heart now. Conditioning, stamina, desire. GGG 10-9
(GGG ahead 97-93)
Round 11: Golovkin being smart, never stopping his advance, engaging Canelo who needs a knockout or stoppage on my card now. GGG 10-9
(GGG ahead 107-102)
Round 12: Alvarez slips to the canvas but then produces a lovely uppercut. Both exhausted but still battling, but the better boxing from GGG. Alvarez makes another huge effort, power shots winging out. Massive effort from Alvarez but too late. The animosity is gone as they engage. Canelo 10-9.
Gareth A Davies has Golovkin winning by four rounds 116-12 but very similar to the first contest in being very close to call.
GGG 116-112 or at worst 115-113 but it was a close fight and a better Canelo performance than first fight— Gareth A Davies (@GarethADaviesDT) September 16, 2018

What GGG and Canelo said
Golovkin did not hang around leaving the ring shortly after the judges decision was announced. He later said:
"I'm not going to say who won tonight because the victory belongs to Canelo according to the judges.
"I thought it was a very good fight for the fans and very exciting. I thought I fought better than he did."
Canelo, meanwhile, set up the possibility of GGG vs Canelo part III. He said:
"If the people want a third fight, we will do it again. But for now, I want to enjoy the moment with my family and my people.
"But if they want us to do it again, no doubt. He's a great fighter but I'm a great fighter and I showed it tonight."
How pundits and fans reacted
Quite a few former boxers, most of whom are turned pundits, had GGG edging the 28-year-old Mexican. Other big sports names just soaked up another night of sporting drama.
I just can’t see that result - canelo did a great job, but he didn’t do enough to win in my opinion - great fight, but GGG can feel that decision should have gone his way - no 3rd fight for at least a year guys (long rest) �� #GGGvsCanelo2— Audley Harrison MBE (@audleyharrison) September 16, 2018
In hindsight alot of the rounds were close. I edged GGG but can we please applaud the smaller man Canelo's chin ����— Carl Frampton MBE (@RealCFrampton) September 16, 2018
What a fight #CaneloGGG2 I gave the fight to Canelo. It was toe to toe action, Very exciting. Canelo surprised us all with the come forward pressure game plan. Well done to both Canelo and GGG. Boxing needed this @HBOboxing@GoldenBoyBoxing— Amir Khan (@amirkingkhan) September 16, 2018
I actually thought it was close but still had GGG taking it by at least two rounds. Both fighters came to leave it all in the ring! #GGGvCanelo2— Lennox Lewis (@LennoxLewis) September 16, 2018
What happens next?
Canelo has already opened the door to creating a trilogy in the enthralling series. At 36-years-old time is running out for Golovkin and any potential rematch is unlikely to be signed, sealed and delivered in the next 10 months. A dream for promoters and broadcasters would be to rearrange the third part of the duel this time next year.
A third fight would be well received by boxing fans around the world and, if his body is still up to the task, Golovkin would be desperate to go toe-to-toe with his great rival again to seek revenge. Watch this space.
