Bob Clampett's 'The Sour Puss' is at its best when its being surprisingly gentle and leisurely. It takes a good few minutes to build up to the main plot of a fishing trip and Clampett restrains his usual frantic pace for some very nicely executed gags. Porky's impersonation of a fish has to be seen to be believed! In these opening scenes we are introduced to Porky and his fish-loving cat as they decide to go fishing. We then share a partially sleepless night with the characters before finally arriving at the lake. At this point, however, 'The Sour Puss' takes a turn for the worse. The character of a nutty flying fish is introduced and with this comes the recognisably crazy pacing of a Clampett cartoon. Unfortunately, the fish character is an immensely annoying carbon copy of very early Daffy Duck and we get another run through of the formula from Tex Avery's 'Porky's Duck Hunt'. This scenario had already been replayed and perfected with Avery's masterful 'Daffy Duck and Egghead' and 'The Sour Puss' feels like the studio is treading water, recycling scenarios with inevitably diminishing returns. The flying fish is not only annoying and occasionally poorly animated, he also completely takes the focus away from Porky and his cat who had previously been carrying the film very nicely. 'The Sour Puss' ends up being a cartoon that falls apart when its main plot rears its ugly head, the character that was meant to be its trump card proving to be its downfall.
