Agreed that the premises sound like fanfiction at best, but I really liked the execution of OotS and SoS. I was at the edge of my suspension of disbelief though, can't deny that.
RoP? That took me over the edge. Too many things wrong with it. Nicely written parts and the Alien was treated well, but when you keep making mistake after mistake with the continuity which could've been easily fixed if you just watched the bloody movie a few more times, I'm simply not on board.
I'd really like to ignore that book entirely, but it influences one of the movies more than any other. That's why, for all the silly things we see in the Rage War Trilogy, I still like it a fair bit. Some crazy ideas: some cool, some ridiculous but it doesn't step on anybodies toes for the most part.
I like the idea of seeing WY employees racing each other to get an Alien specimen and, of course, it blowing up in their face so so bad. Some good drama could be done there.
