What kind of impact does Hollywood have on video gaming

This is something that's been festering in my mind for quite some time now. I've noticed that so many people out there are willing to believe Hollywood is covered in creative power, and video games simply leech off of their success.

Here's what i mean.

I recognize that movie games (e.g. Finding Nemo, Shrek, The Da Vinci Code) get made, and i recognize that game movies get made (e.g. Resident Evil, Silent Hill etc...). Attitudes towards movie games are never very high. Myself included, as well as my entire family. Once me and my sister were renting a movie, and she noticed in the video game section there was a Finding Nemo game. She was disgusted and was a little mad that they "ruined" a perfectly good movie.

This attitude spreads further than it should though. There are many people out there who don't believe in game movies. Just a month ago i was at the mall with a friend who doesn't know jack about video games. We walked into the Sony Store, to browse around for new stereo systems. There was a display case for the PS2 Slim, and a few games displayed along with it. One of which was Silent Hill 3. The first thing out of my friend's mouth was a disgusted "They've already made a video game out of Silent Hill?" I thought he was joking at first before i remember that he doesn't know jack about games, and came to the shocking realization that he was serious. I had to educate him.

Another example was when me and some friends were renting a movie, and she saw Resident Evil for the gamecube. The first thing she said was, "They shouldn't have made Resident Evil into a game, it was such a good movie." Once again, i had to educate.

Long ago, i had friends musing over "Why they made a Final Fantasy game out of Final Fantasy: Spirits Within, it wasn't even that good a movie." Once again, i became teacher and had to to teach them which came first.

A lack of simple research due to a lack of interest in video games obviously creates the idea that video game studios constantly leech off the creativity of Hollywood, when it is not the case. As Hollywood continues to make more and more game movies, this will continue. Am i the only person who notices this/cares? Or am i over reacting?

Jam it back in, in the dark.

What you've said above is interesting, and has much merit, but it's not quite what i'm asking.

I'm bringing to attention the fact that people who avoid video games see game movies come out, and don't realize that it was first a game. Later on they hear that there's a game of it, and they immediatly assume it's one of those rushed out games to try and feed off the popularity of the movie, thus perpetuating their distaste for gaming. Does that make sense?

There's nowhere I can't reach.
