I honestly don't understand the logic in that though, a fan film, no matter how good shouldn't affect the sales of an official product. I mean most audiences would still go to see an official movie in theatre or buy the bluray/book/comic/game. At least I would have thought so.
Maybe fanfilms... but fan games? Anyone remember that Aliens vs Marines mod for the AVP Classic? It looked insane, hell I can't find it on youtube anymore since Fox seems to have purged all traces of it but I remember thinking how the "official work" looked a shame next to it.
But back to fanfilms the fights on AVP Redemption were more creative/interesting than the ones on movies. Plus despite being CGI, the aliens were biomechanical which already makes them more pleasant for me to look at than the ADI ones.
Fanmade stuff can have a lot of potential.
Thank you for having an open mind. I can't tell you how many times I've had people say it's a stupid idea and that I (or other fans) could never write or produce anything of value.
There's a pretty big stereotype around fanfiction and the like. It's not exactly wrong, but it's also not cool to automatically assume that it's going to be bad without actually looking at it. I'm quite proud of the stuff I work on.
