Tron is about a computer games developer who gets sucked into an alternate reality world (created by him only) and never returns and how 'accidentally' his own son gets sucked into the virtual world, where he fights a battle to rescue his father and his (future) love interest (if a sequel comes out) from a 'program' (which looks like his father).
The movie is all about how cool the sci fi stories are. It takes its inspiration largely from Star Wars and the Matrix. Even the costumes look too similar to the epics. The Hero's father looks like obi van and the villain looks like darth vader. There are references of calling the virtual grid as the 'grid' (The matrix types) and then even the bad guys are nothing but 'programs' (Agent Smith types). But the movie definitely takes the concepts a couple of steps further by redefining 'cool'. The costumes, the cars, the bikes, the interiors are just killer and you go 'wow' at more than one occassion.
The word 'awesome' falls short of describing the first fight sequence. Small sticks transform into bikes by clicking a button and every turn you go 'wow'. Sadly post this sequence the movie goes into a boring description of what happened, why it happened, how it happened etc etc. And you almost feel like going out and grabbing some popcorn. The movie just doesn't go anywhere from there. You keep expecting it to surprise you even till the end but it doesn't.
If you have to take one thing out of the cinema hall that is the background score by Daft Punk. With all those techno sounds in the fight sequences and heavy opera style score while approaching a fight scene, it reminds you of Hans Zimmer's The Dark Knight score at more than a couple of places. I think the movie would have fallen flat on its face, had the sound track not been as good as it was. Makes the movie, A Definite watch from a 'Watch it on TV'
Overall: The movie is pretty good when it comes to the action sequences, the 'cool' factor and the background score and scores really bad on the story/script/direction front. A Definite watch if you are an adrenaline/sci fi junkie. Avoid if you are not.
Feel-O-Meter: 6.5/10
