Have you ever had a conversation with a friend about which of your favorite books, video games, comic books, cartoons, et cetera you'd like to see made into a movie?
Of course you have.
You know the part of the conversation when you come to your senses and say something along the lines of "Yeah, I'd really like to see Captain Carrot and the Amazing Zoo Crew made into a movie, but they'd probably fuck it up like they did with Resident Evil"?
Isn't that a god damn crying shame? We're so used to being disappointed that we'd just as soon give up all hope that something will be worthwhile as even bother to hope for it to be good.
That's why the film industry is a bastard.
Then you have to ask the question, "Well, why do we put up with it?"
The simple answer is that we'd have to back up our convictions that the majority (note that I did not say entirety) of movies these days are shit. Specifically those based on intelligent properties that originated in other forms of media. However, this is next to impossible when a staggering percentage of the movie-going population still throws their money at them regardless of the quality.
And therein lies the problem. As I've stated before (in my rant about films based on the works of Philip K. Dick), we've stopped demanding quality and started accepting mediocrity.
By the way, you can have as much fun watching the Resident Evil movies as you damn well please, but if you actually think that they're an improvement upon, or even a good representation of, the source material, chances are I don't like you.
Sorry, but it's your own damn fault.
