Unlike a lot of people my age, my first experience with Robin Williams was in Mork and Mindy. I watched a lot of Nick and Nite as a kid. As a weird, hyperactive child, I had such an affinity with Mork, though I wasn't remotely conscious of it at the time. This might sound strange, but I really do feel like Mork was a positive role model for me growing up.
And then there was Hook, and Aladdin, and Jumanji, and Mrs. Doubtfire. Hitting high school age, I saw him in more dramatic roles - Good Will Hunting, Insomnia, Dead Poet's Society, Awakenings. (Dear God, was he wonderful in Awakenings.)
One of my little sister's favorite movies is RV. Not one of his most critically acclaimed roles or films, not by a longshot. But I've seen it probably ten times with her, and every time I watch it, the scene where he's typing up his report and climbing on top of things trying to get cell phone reception makes me laugh even harder.
There are still many movies of his that I haven't seen. I think it will be a little while before I get to them.
I saw a comment somewhere yesterday that put it best for me. Robin Williams wasn't just an actor, and he wasn't just a comedian. He was a part of our culture.
I just miss him so goddamn much.
