The Bosko cartoons may not be animation masterpieces, but they are fascinating as examples of Looney Tunes in their early days before the creation of more compelling characters and funnier and more creative cartoons.
'Bosko Shipwrecked' generally to me is one of the better Bosko cartoons. Not a great cartoon, but a decent one. As ever with a Bosko cartoon, the story is slight, would actually agree that it's even more slight and more generic than usual. There are mostly inventive gags here, but not as a consistent whole, with a couple of others forgettable and tired in timing. The stereotypical character of the Cannibal King won't bode for all taste buds, from personal view he was unappealingly drawn and not remotely amusing at all.
On the other hand, the animation is good. Not exactly refined but fluid and crisp enough with some nice detail, it is especially good in the meticulous backgrounds and some remarkably flexible yet natural movements for Bosko. The music doesn't disappoint either, its infectious energy, rousing merriment, lush orchestration and how well it fits with the animation is just a joy.
As aforementioned, most of the gags are quite inventive, Bosko while not a great character is more compelling than usual and the pacing is lively enough.
In summary, decent if not great Bosko cartoon. 7/10 Bethany Cox
