Mouse into Space is not the worst Tom and Jerry cartoon(a serious contender for that dishonour is Switchin' Kitten), however it is still a very poor cartoon that starts off badly and goes down rapidly downhill from there. In fact for me the only redeeming quality is that it is fairly short.
The animation is just horrible. If you want flat colours, badly drawn characters and static backgrounds look no further than Mouse into Space and any other Gene Dietch cartoon for that matter. The sight gags are poorly timed and unfunny, the pace is increasingly uneven and the story is not entertaining in the slightest.
I haven't even got to the worst of the problems yet. The violence is once again sickening and made me feel uncomfortable- only Switchin' Kitten, Sorry Safari and It's Greek to Meow! are more uncomfortable to watch- and the music is very forgettable and annoying. Worse is the stomach-churning sound effects and the gross distortion of the characters, neither Tom and Jerry are that likable here and their personalities are way off the radar.
All in all, poor. Not the worst, but best avoided. 2/10 Bethany Cox
