From what I heard, the few people who went to see it absolutely loved it and said it was destined to be a cult classic, but it wasn't getting that same respect from critics.
I could be wrong on this though, I'm just going by what I've read on the Internet which is almost certainly bullshit (and written by salty BR2049 fanboys).
It could be a regional thing too to be fair, the critics over here were saying that it was a worthy sequel and how great it was, I don't remember seeing a bad word against it (except a few people decrying the running time).
