I watched this on a flight to San Francisco a few weeks ago. I read and really enjoyed
The Midnight Library this summer, which has a similar premise, so I was intrigued when one of my daughters and her boyfriend described this film to me.
I agree with a lot of
@Palatine 's post, except I don't think it was a failure; I just think it could have been much better and tighter. But I wanted my wife to watch it on the way home (in part because the mother-daughter relationship bears some resemblance to hers with one of ours), and she did exactly what
@nwhoopfan did, i.e., turned it off after around a half hour because she couldn't get into it.
The length and repetition probably would have bothered me a lot more if I wasn't watching it on a cross-country flight. That was actually a positive though, because it occupied me for almost half the flight.
I'd give it 3.5/5 stars.
