If you know the old cartoons of Tom and Jerry and expect something of that quality and characteristic humor, then you will be horribly disappointed. This movie has NOTHING to do with the known characters of Tom and Jerry. Even the way they are drawn is cheap and slightly wrong. The movie is clearly just and only using the names of two of the most famous animation characters of the past in the hopes to draw a large public, but isn't even TRYING to create the same characters.
Ever seen a boring animation series? This movie makes me think of the earliest of animation, like Mickey Mouse and the Steamboat. For a while you wonder why the story doesn't make sense, and then you spot the reason: the producers, no doubt in an attempt to save money, couldn't afford a music writer: what they did is buy a CD with some existing classical music and then created the movie AROUND it. Concentrating mostly on having the rhythm and high-lights in the music correspond with the rhythm of moments of action in the movie. The result is an artificial story line that seems to rotate around nothing. Okay, so they travel from spot A to spot B, that is plot, but the details of the travel is boring, boring and boring. Once you realize that every event is written into the movie solely due to the RANDOM fact the existing music is doing something you can't help but realize that your looking at some time-filler. I really couldn't finish watching this horribly boring movie. I watched until they got on some frozen river, no doubt only written conveniently into the plot because the music made them think of gliding motions, and then quickly jumped forwards through the movie, hoping to see a glimpse of the old Tom and Jerry, were Tom is trying to catch Jerry using evil genius and the weirdest of self-made equipment. Where both, Tom as well as Jerry regularly are deformed, for example splashed flat against a wall, or getting the shape of a cube after swallowing one the size of themselves, or losing all or most of their hair, only to be completely restored again the next scene.... but no, nothing of that in this cheap, boring animation, that has NOTHING to do with Tom & Jerry.
