Well, this discussion is about our opinion, so mine may definitely differ from yours. I'm just pointing out what I personally saw and think, answering the OP and carefully choosing words like "personally & I" among others. I compare earlier RE games with similarly designed games that used similar controls (Alone in the Dark, Silent Hill, Dino Crisis, Fear Effect to name a few) and they were fine because, IMO, the overall design, mostly the fixed camera angles, was better suited for tank controls, like corridor encounters were as well, like the slower pacing, puzzles etc. RE4 isn't really comparable to earlier titles in that way, my complains come in comparison to other 3rd person shooters and more action-oriented games like RE4 is in reality.
During my entire playthrough, original release week, I was wishing RE4 would have controls like Dead Space got years later. That doesn't make RE4 bad, it's just one part of the question "why" asked in the OP that I just can't answer.
