This movie is great! Especially the human family characterization is just amazing, maybe sometimes it loses too much time with the slapstick humor, but it's never annoying and it made smile at time. A funny, cute and sometimes even smart (I mean, the running jokes about mosquitoes are genius) Movie. At times it somewhat reminded me just a little of Miyazaki's stuff (but with Russians alien).
Italian Neorealism meets Studio Era Creature Feature. My latest revisit, a first in 8 years, I have found that the film is actually pretty dark and incredibly sad, while also meshing strong comedic writing in the mix. Possibly the strongest work from Disney of the aughts, including even Pixar.
