I personally loved RE0 more than the REmake. Because the puzzle elements were well implememnted. The story line answered alot. And the removal of those god forsaken item boxes.
The control and camera angles are classic Resident evil style. If you even owned any of the titles for ps1 you'll know it well. It takes getting used to and it adds more strategy to fights (as in, I'd better avoid that crimson head I can barely see him over there but he has yet to notice me, and will thrash me if I'm not fast.)
The fixed camera angles were put into Re1 to give it that distinct Horror-movie feel. They also made the presentation of the graphics on the Game cube better IMHO.
The Re4 style is a new direction they went with to include more of an action oriented plot then a survival theme for the new games.
Re5 will most likely follow the new formula. It looks more like Re4+Black Hawk Down+28 Days Later, set in Africa. The 'survival-horror' aspect for the new game will be 'fighting impossible odds' kinda like Nemesis. They're supposed to be an overwhelming mob of fast moving "zombies" that you would be better avoiding than standing and fighting it out.
