I haven't read the book, but her mum didn't seem in any way not nice to me
DS has AS and is much less affected by autism than I know Temple Grandin is (I have read about her, just not her stuff) but some of the stuff was definitely what I see in him, when she got to the ranch right at the beginning and couldn't link her talking about opening a gate to opening the gate in front of her, the conversation about her squeezing machine with the counselor or psychiatrist (or whoever that was) where they were talking at complete cross purposes and the meltdown she had at the party were just so my DS.
I though Claire Danes did an absolutely fantastic job, I know she spoke like Temple does and again very similar to my DS, but other things as well, I noticed the way she ran and facial expressions, especially her eyes were again exactly what I see in my DS.
Temple Grandin is absolutely inspiring, but I knew before watching it that it was going to end well, but I was really interested in how they were going to portray it all, her autism and her success and I loved it.
I'm slightly worried now that children with autism are all going to be expected to have photographic memories because that wasn't explained that well, but that's really my only gripe and not a major one, lol
