Well I think RE4 and RE5 are very alike, and I didn't like em' as much as RE1 to Code Veronica because they were more action. What I loved about RE5 though was that it had co-op that worked. They need to try to create more co-op horror related games like this, only better.
The old Resident Evil games were awesome and I would really like to see a new RE in the old style My favorite one from the old ones was Resident Evil 3:Nemesis.
I don't totally dislike the modern Resident Evil games. It's just that the first five or so games were entertaining and had good suspense and characters. RE4 felt a bit off track. But no less fun to play. I like how you can play as Ada after finishing the game as Leon.
I like RS4 , though I have never played any other game of RE ( had played RE DEAD AIM .. but that's 3rd class ) .. RE5 have CO OP ! That's great! would have to buy it then
