It's Texas Chainsaw Massacre meets Saw meets every found footage movie, meets every other horror movie ever made. It would probably be easier to list famous movie properties that RE7 doesn't take direct inspiration from. I don't think I saw any Care Bears in there, but I might've missed them.
If there's one thing that you can't call the Resident Evil series, it's stagnant. Every couple of entries they habitually toss everything out the door and keep things fresh, with only a couple of connecting points between them. Umbrellas sometimes show up, sometimes a returning character might get jostled out of retirement for a check, so on.
RE7 takes that a bit further, and RE7 itself tosses itself out habitually to just be a new game. After a hideously prolonged, hyper-cinematic, mostly hands-off opening, you're tossed into some sort of Condemned meets Outlast run, hidey survival horror affair, until finally you're just mowing everything down and facing off gigantic bosses.
I think it's pretty impossible to play this game and not have some significant issues with some major portion of the game, because it's just trying to nab too many audiences at once, and the end result is that you'll probably enjoy about 30% of the game and find another 30% tolerable. The last 30%, whether that's the runny hidey bit, or the cinematics and shallow puzzling, or the combat gauntlet, that'll probably irk your senses. Chuff your muffins. Slap your biases.
The 60% that you do like, you'll probably like quite a bit. I thought the movement speed was too slow, but that the combat was fun and that the puzzles were fun, but didn't care for the "let's pretend we're not a cutscene so you can't skip" opener or runny-hidey bits.
It's a buffet of a game, where you're legally obligated to take one of everything there instead of just going for the bits you do like. What's there is good, nice atmosphere, sounds, the two enemy types are a bit laughable but I enjoyed using the upgraded guns on them, but it's not a game I ever see myself replaying, or recommending with any enthusiasm.
You'll probably get caught in the giant net Capcom is casting to get the widest possible audience, give it a look - but the result is that there's going to be giant stretches you're checked out during.
