Why introduce the sweater thing as a thing at all if you're then gonna ignore it ? I don't know much about autism other than the spectrum is big and they like their routines. But I feel like those two things are huge.

Her condition would have been better portrayed as it is in The Good Doctor. As it was, half the time I forgot she was supposed to even be autistic. She just came across as awkward and antisocial, which are personality traits that don't actually mean a person is autistic.

Also, the ending didn't resolve much. Did the sister sell the house? (it had a for sale sign on the lawn in the last scene with the dog). If she didn't, the how did she afford to keep it when she couldn't before. Did she and her husband move wherever they were supposed to be going in the beginning? (was it supposed to be far away? Because, it kinda felt that way, like the sister was saying goodbye when she went to visit Wendy, and they couldn't take the piano with them) Did Wendy move in with them, or did she stay in the other house?

I feel like this movie had a lot of build up, but little pay off. She entered her script and lost the contest, fine. But what about everything else?
