Like the first Tron, a visual treat with a simple story. It trades the neon-expressionist world of the first for one that's slightly more solid (but it works).
They try to make Sam cool by having him parachuting off of buildings and being a biker n shi, but he still can't come close to the inherent coolness of Jeff Bridges.
The de-aging works for Clu (for story reasons) but when they use it on Flynn it makes me cringe. It's really the only flawed effect in the whole film. The rest is gorgeous.
