If you're into high adrenaline filmmaking, run, don't walk to see Rollerball. It's quick, tells its story, tells it well, and gets out. No lingering on extraneous backstory or exposition. The "corporate" message from the original is solidly packed into a screamin' 90 minutes.
Any holes? Who the hell knows? There isn't time to consider any before you're swept off into the next sequence. Big movie. Damn, McTiernan is good.
