I watched this film as a joke with my girlfriend, as both of us were looking for something really awful to laugh at. Sadly, the movie wasn't that funny and really wasn't that poorly made either. Now, that certainly isn't a bad thing, and I would've been very happy had the film been good. Unfortunately, the film's biggest problem comes from the fact that it's way too boring and serious for its own good.
Now, sure, the film is about a gang of token puppers that get lost in space, and there are the occasional fart jokes (the "fat" dog gets most of the abuse here), as well as a few puns (they say the phrase "one small step for dog, one giant leap for dogkind" at least five times), but other than that, the humor is almost non-existent. The script almost feels like it was written for adults staring adults, but someone decided to change it to a G- rated talking dog movie at the last minute, forgetting to remove all the long and boring science talk scenes. Trust me, there are a lot of long science talks sequences. Every time we cut back to the humans on earth, there's always a large spiel of exposition explaining the scientifics behind what's going on in space. Kids don't care about scientific details or the true-to-life accuracy of the facts, they want to see silly puppies doing silly things. And even when they cut back to the dogs, it's mostly serious dialog discussing their situation. Sound exciting to your kid? Probably not. The film is also unnecessarily cruel to a Russian who gets abandoned in space and tries to get revenge on the puppies after they nearly blow him up in a fiery explosion. Seriously.
That's about it. Also, the rapping wigger dog is probably the most annoying character in the history of cinema, and I do not approve.
