Lack of story depth (improved a bit in the transition from RE to REmake)
Horrible voice acting (greatly improved from RE to REmake)
Pointless puzzles (more added in REmake ) Though to be fair the whole game is "one big puzzle" if you think about it.
Weak "Bosses" (other than Plant 42 I didn't find them very challenging)
That's all I can think of off the top of my head, I'm busy doing other things at the moment, so that's the best you get for now.
Personally I've never understood the complaint about the controls. It might be challenging to get the hang of with a DPad, but it's pathetically easy with a stick.
As for the camera angle, this is a cinematic game, not a FPS.
