Every character in this movie is lovable and it wasn't as much as a comedy as I expected since it made me cry a lot after it was over. Maybe the relationships of the characters and their parents really hit home for me, but it was definitely worth the watch. I liked the strangeness of it, and usually I will shy away from movies that are strange just for the sake of it. The characters in "Gigantic" were very human and the awkwardness is easy to relate to.
I don't really know what other movie to compare it to, I'm not good at that, but I liked it and it's worth a watch if you're looking for something to watch on a rainy afternoon. It kind of had a Todd Solondz feel to it, but lighter. Have you seen this? What did you think?
