In [some] instances Tom or Jerry will put his love-hate relationship on the line. . . . Sometimes these twists would fail - none so miserably as the late entry Blue Cat Blues, in which Tom and then Jerry plans to commit suicide. . . .
Hanna and Barbera did their last group of Tom and Jerry cartoons in 1955 and 1956. Some of these rank along the best this series had to offer. . . .
[Others] are so bad that it's hard to believe the same people made them. . . .
There is no way to understand how the characterizations could go so far astray. . . . In ... Blue Cat Blues they plan to commit double suicide!
