The Resident Evil fims are not classics nor are they great achievements of our time but they are watchable efforts though. What I don't understand is how one of the best villains in gaming history in Nemesis was seemingly tamed and treated like a pet in the film?

Yes he went after Stars members which is what happens in the Nemesis game but in the film he doesn't look anywhere near as tough as he should have been.

The one scene he had which owned was when he took out the Stars members who were holed up in the building and to be honest the whole film should have followed the game's idea of Nemesis stalking the heroes as the story went on and appearing at random to attack them.
