Will adults want to see this?

The movie is aimed at adults, which is pretty clear during the first half of the film. It is very dark and morose in the first half and never rises to level of say a normal kids film. What I do think is that the marketers presented a trailer that gives you a completely different film than what you end up seeing. It isn't a bad film, could have used a little more color and better voice actors for rabbit and piglet... but otherwise it is good enough to probably recommend to adults with only a passing knowledge of pooh.

Yep, there were about 30 people in our theater and not single kid or teenager in the audience. We all enjoyed it and it's definitely aimed at adults in a way. Kids will like the "cute" characters but adults will appreciate the message/story and the nostalgia.

No they have other things to do/are too busy

100% yes. In fact, I bet the majority of this film’s audience has been adults.

The film is an all-ages affair, of course, but I’m sure people who grew up with Pooh and the characters will resonate with it the most. To me it’s obvious that was the intention.

Yeah, but not at the cinema
