You have to go in with some love for the franchise, but not an obsession.
Do the goals make sense? No.
Are there frustrating levels? Yes.
But I'm the friggin' Predator. And some of your kill moves are gore-tastic! And despite a few of the frustrating levels mentioned above, the majority of them are simple and fun. Mindless fun, but fun.
It's not deep gameplay, it's not a good plot, but you get to be the Predator. Just that, to me, is fun enough.
It's not going to be a miraculours experience. and if "just being" isn't going to be enough to make it at least a fun experience, then you won't enjoy this game. But I like it.
