To be honest there's no point attempting to compare the recent Resident Evil games with the old ones. You're going to be disappointed.
Take the new ones as their own thing, the "survival horror" we knew doesn't really exist anymore. If you want that, go back and play the old games; they still exist.
I'm slowly playing through Leon's campaign and so far I quite like it, it feels very well done so far.
By the way if you haven't already, play Resident Evil Revelations for 3DS. It's a great combination of scary and action.
