I don't get the hate for this film

If you watch the original Rollerball you'll see why.

There's nothing wrong with this movie. It would probably be between 6 and 7 stars if it weren't called Rollerball. It seems like there's a bunch of people who will 1 bomb a movie if it's a remake, or they don't like an actor or director's personal life, or they've been told that they're supposed to think it's the worst movie and they never even give it a chance.

Agreed. Admittedly, the fake night vision scene with the awful cartoon sound fx is pretty bad, but the rest is okay IMHO. As for bad acting, I must have low standards. My idea of bad acting is someone standing like a statue and reading lines from a card. It really irritates me when someone says "(name) can't act!". Unless they're a successful actor/director/producer they should hush.

The hate is based on the comparison with the original Rollerball (1975) which is actually a quite different movie. The original has a very dark and deep undertone that is not in this one. The remake is more focused on the full tilt action forgetting much of the story behind the original which involves the corporation power and a dystopian society. The action scenes are amazing here but you don't see any love between Jonathan, Marcus and Aurora, let alone the rest of the team like Katya or Toba. There is no character development here and that is why you don't give a damn about Marcus being killed or Aurora being in danger.

That cartoon FX sound when they are escaping in the bike is ridiculous LOL

I watched this one first and to me it is a decent movie (not great but fun to watch), much later I watched the original and I understood why people was pissed off with the remake. The original looks dated of course but the story is way better developed with more dialogue, expressions, meaningful lines, etc.

This film is garbage independent of the original Rollerball, which itself was kind of interesting but not all that great. First on the list of what made the 2002 remake unbearable was the execrable, incessant use of shakeycam and rapidfire edits. Rollerball 2002 is one of the worst offenders of any film in these areas, which makes it nearly impossible to follow what's going on and makes every action scene dull and uninspired. It's a great way to avoid doing any real stunts or expending the slightest bit of brainpower on cinematography, but ultimately cheap and fake.
