I loved that movie too. It wasn't critically acclaimed, but it's the audiences that really determine a movie's success. And I've met like two or three people who didn't care for it. I'm sure that contrary crowd was just a minority. But I enjoyed Mrs. Doubtfire a lot.
Mrs. Doubtfire had to be my favorite and most watched movie from Robin Williams as a kid. Love that movie so much. I actually didn't watch a bunch with him, but the few movies I watched him in were amazing. Mrs. Doubtfire, Aladdin, Hook, Night at the Museum, Popeye. I really should check out some more movies with him... even, though, I'll probably cry if I watch them.
