I am a huge fan of Tom and Jerry, and while this is not the best, it is an improvement over weaker Chuck Jones-produced Tom and Jerry cartoons such as Matinée Mouse and Shutter Bugged Cat. Jones's work with Tom and Jerry is uneven that I do agree with, but they sure are better than the awful Gene Dietch cartoons.
Duel Personality is a little too short and perhaps a tad too quick, but a lot of it does actually work. The animation is surprisingly not too bad, it is for me one of the better-looking Chuck Jones-produced Tom and Jerry cartoons, while the music is jazzy and upbeat. The story is interesting, while the sight gags are very funny and delivered at a good enough speed.
In conclusion, not bad at all, as a matter of fact it is surprisingly good. It isn't outstanding, but I can think of a lot worse to spend my time. 8/10 Bethany Cox
