I can't speak for "people", but I never saw any of the Potter's in the cinema (I do have the collection on Blu-ray, and rate it very highly from Azkaban on. one of the best film franchises ever seen, frankly, in terms of tonal cohesion, world building, characters [minus The [Boy-not-Girl] Ginger One] and so on), so even though I like the look of Fantastic Beasts I never intended to go see it.
I'll rent it, at least (every source I trust/pay attention to really enjoyed it), but I doubt I'll buy it.
Not overly keen on Eddie Redmayne as an actor, and I'm not keen on the American setting. Or the word no-madge/no-mag/no-maj. Oh, and Johnny Depp's in it, and fuck Johnny Depp. That guy needs to be forcibly stopped from ever acting again...

I didn't go to see it because I'm just... bored with the Harry Potter universe, honestly. JK's constant updates post-finish and the pretty... low-quality of those updates really burned me out on any interest, and the rather 'Standard Hollywood Design' of the movie killed the rest of it.
Wasn't Cursed Child received very well? I'd guess if they adapted that there'd be more buzz about it than Fantastic Beasts, Where Are They - They're Probably In The Case.
