If I recall most PS3 exclusives never review great but a lot of them become classics. For example, Resistance and R&C, I don't remember a lot of reviewers loving either series but God knows fans did. I don't think review scores really matter that much when you look at the variety of games. Everyone knows Microsoft will give you a game with pew pew and rev rev and Nintendo will give you jumping and smashing things, but Sony always seems to be taking chances. Heavy Rain, SotC, LBP, Demob Souls, etc. I like Knack, I like KZ, and I like Infamous. Reviews did not deter me nor make me second guess my purchases nor experiences. The fact is I make my own decisions and when you own over 200+ games like I do from pretty much every genre except sports, you appreciate variety. Once day I play a tales game, one day a platformer, one day a racer, one day a shooter, etc. I for once will probably love The Order because it looks like a solid TPS, with Steampunk + Rssistance 3 elements. Will it be for everyone? No. But will it have its huge fanbase? Definitely whether or not reviewers like it. Just saying, don't rule out the game yet. Ramble ramble.
Tldr; give it a chance.
