I found Unicorn Store as well. I haven't seen it, either. I looked at reviews, though, and amusingly the top "good" review repeatedly said that it was, objectively, a very bad movie but that they liked it for reasons.
While I’m at it, I guess this is as a good a place as any to discuss my feelings on Brie Larson. I’m not one of those people who hate her with a burning passion and, in my opinion, I think she’s getting too much hate than she really deserves... but at the same time, she doesn’t make it easy. I can see why people dislike her so much. I also thought she was pretty bad in Captain Marvel, but I did like her in Scott Pilgrim, before she became famous.
For me Captain Marvel is by far the least entertaining of all Marvel movies, even worse than Thor 2, Iron Man 3, and Black Panther, and IMO this is chiefly because Larson in the lead is just so aggressively unlikeable. All of the other MCU movies have likeable leads. I saw her in Room and thought she was awful in that, too.
In my opinion that was a poor decision. And it would make a lot of economic sense to recast the role. But I wouldn't say I hate her passionately.
