I watched Inside Out this week too.
I didn't like it as much as everyone else seems to. I thought it was very clever, and i enjoyed all the bits inside her head, but i found the whole rest of the film far too miserable. I really don't like sad films, and this one seems pretty damn gloomy right from the start. It seems to be the way all Pixars films are going these days, which i think is a shame.
That said, i think it definately deserves a rewatch, just to catch all the clever references etc. It was a bit like Inception for Kids.
