Indeed it is. And Temple Grandin herself has commented about how dead-on Claire Danes's depiction of her is. Check out the DVD extras.
Temple Grandin is an outstanding individual, what she herself calls a high-functioning autistic. But don't walk around behind her when she's giving a talk; she spooks like one of the cattle she's so in tune with (and she makes no bones about it). Any time you can see her in person or otherwise, it is a worthwhile experience. Read her books too.
