Completely agree. This is a great scene to study to identify Tron Legacy’s shortcomings as well as strong points.

• 0 - 13 seconds in: establishing shots are solid
• 14-17 seconds: the landing. the guards seen approaching through the skylight is good, but the guard crashing into the partygoer and derezzing him at 17s is a little hard to follow
• 18s - 24s: chaos, the guards loading their weapons while Daft Punk starts the music is all good. it’s a little weird that of the four guards, one of them has no weapon and the one on the left just has a small “nunchuck” style weapon - it’s still cool but not as much as it could have been. Also, Daft Punk seems detached from the scene, as if it’s obvious that they were shot at a different time.
• 25s-48s: general fighting. It’s solid but not amazing.
• 49s-1:01: faux-Bowie taunts Son of Flynn and SoF’s waifu appears. the clash at 58s where waifu holds off two guards is a cool idea, but the physics of it are unconvincing. faux-Bowie’s cackle seems forced.
• 1:02-1:09: brief combat, well-done. Cringe line by SoF “I’ve met your friend, he’s fantastic” – why is this even needed? This might be a good time to say that one of the charms of the original Tron was that the actors looked like regular people rather than Hollywood B-listers.
• 1:10-1:34: combat, moderately well-done. faux-Bowie does a good job with “Behold the son of our Maker” but does a somewhat cringe air-guitar, and shoots lasers out his cane which seem to do nothing. At least Daft Punk is briefly contextualized in the scene.
• 1:35-2:00: this segment begins with a scene that could be touching, someone mourning over the fragments of their derezzed friend. However, it’s hard to understand what’s happening there on the first viewing. Also, faux-Bowie does some kicks. SoF winces melodramatically. Two guards hold waifu’s arm out while they derezz it (and nothing else) which seems overly complicated.
• 2:01-2:24 Flynn appears dramatically. Great lighting. Faux-Bowie retreats.
• 2:25-2:38 Flynn speaks, sounding like a California beach bum. SoF picks up his waifu and Flynn follows, his arms spread dramatically like he’s Naruto-running. At 2:35 a bald person kneels in prayer, which would be cool except it’s not obvious why they’re kneeling (presumably to Flynn?)
• 2:39-2:52 A guard steals Flynn’s frisbee, and plants an explosive which detonates – this sequence is great. The size of the explosion at 2:46 make it look like the entire back of the club might be taken out, along with everyone nearby. But at any rate the elevator plummets.
• 2:53-3:01 Oh, looks like the club wasn’t taken out, nor was anyone nearby. Also, faux-Bowie reappears. He derezzes one of the guards – it’s not immediately obvious from the scene at 2:54 that he shot the guard from behind with his cane, but on several viewings it looks like that’s what happened. faux-Bowie saunters off in a somewhat amusing way – he’s still “trying too hard” but he’s got the right idea. -3:02-3:30 The elevator falls. Some nice external shots, though it’s hard to care about what’s actually happening inside.

In general, the music and the set design carry the scene. This is an example of why chaos is so hard to choreograph well.

when the music kicked in she stood up and started dancing!

This is awesome, my niece did the same thing the first time I played Kraftwerk for her at that age. Kids, they just know.
