But I've now seen it in full almost 3 times and I like it a little more after that first viewing.
The first time through it, I hoped for bigger laughs and its lack of big laughs (other than the penis jokes) disappointed me more and more as it progressed.
After finishing the disappointment start to end, however, it's much easier to enjoy it for what it is. There are subtle laughs throughout and the true comedy of the movie is the movie in its entirety.

My 6 year-old daughter just pulled me to her TV so I could watch the run-away hamster wheel bit again. Sigrit's facial expression when she starts singing again after getting dragged off the stage by her neck is wonderful. Her eyes are so big. Wonderful.
