It was easy on first watch to have fairly low expectations. Have said more than once about actually liking Popeye as a character and many of his cartoons are good to excellent. 'Doing Impossikible Stunts' was a cartoon though that was made when Fleischer Studios had declined drastically (except for the Popeye theatrical cartoons). Also because it was a compilation cartoon, often referred to as a "cheater", so it was hard to not question its point.
'Doing Impossikible Stunts' was actually better than expected on first watch, while nowhere near close to being one of the best Popeye cartoons. On rewatch, when rewatching all the Popeye cartoons again late last year, my feelings are the same. Maybe it is on the pointless side and the framing story is not near as good as the cartoons featured, but as far as the Popeye compilation films go 'Doing Impossikible Stunts' fares favourably. One of the primary reasons being that the featured cartoons are all very good to great and come from the series' best overall period (mid-late-30s). The cartoons in question being 'I Never Changes My Altitude', 'I Wanna Be a Life Guard', 'Bridge Ahoy!', and 'Lost and Foundry'.
Could 'Doing Impossikible Stunts' have been better? Sure. The framing story is very predictable (a very familiar setting done not enough with), doesn't have enough funny moments and the material is very seen it all before.
The animation quality, while still fine actually, is not quite as good in the framing story as in the featured cartoons. Not as fluid and it doesn't look very imaginative, whereas there were a number of clever touches in all four featured cartoons when things were more frenetic. The supporting characters in the framing/wraparound sections don't serve an awful lot of point with too little done with them.
However, the animation is lively and nicely detailed enough. The music is consistently wonderful throughout, with its usual lushness and playful character that adds so much and synchronizes so well with the action. The cartoon never stops being entertaining and the best of the many gags and snappy dialogue and asides are extremely funny.
A vast majority of the cartoon has a lot of energy, even though the framing story is nothing exceptional but this is on the strength of the clips being so brilliant. The end twist is also very inventive. Popeye is amusing and likeable, voiced wonderfully too by the definitive Popeye voice actor Jack Mercer.
Summing up, pretty decent if not great. 7/10
