Query: Fun movie, but a bit short. (Also, I think "IMAX Cuttlefish" would have been a more accurate title...)

I enjoyed this movie overall. It definitely showcased some fun things I haven't seen in documentaries before. Also, it was nice that they didn't abuse the 3D the whole time, but they also certainly didn't ignore it (like some other movies reportedly do). The movie is only 40 minutes, but after ~15 or so the 3D started to seem quite normal. And, unlike some other reviews, I found the commentary to be fun and enjoyable.(FWIW, I got this for free by buying an LG 3D Blu-ray player. However, I probably wouldn't value it at much more than 15 bucks...)
