This is the worst movie in the series, easily. Afterlife/Retribution suffer from gimmicky 3D effects, but this movie was just purely cheesy, full of holes, inconsistencies, and was simply uninteresting.
It also suffered heavily from being a product of the early 2000's.
The first movie at least tried to take itself somewhat seriously. This? Was a joke. I've always liked the RE Franchise, but this this movie is hard to watch.
... and that's after just watching it again tonight. I fell asleep once. Rewind. Almost just turned it off and went to #3, which was a much better movie.
I feel like this movie gets worse ever ytime I watch it. Other than Jill Valentine's look, I can't think of anything I like about it. Just changed my IMDB rating to a 3.
