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. There are some good cartoons, as well as some average or less ones.
Some of Bosko's cartoons are good (with the animation, music and some well done gags often standing out as particularly impressive). Others are average or less and hindered by lack of laughs, lacking stories, struggling to have enough material to sustain even the short running time and the limitations of Bosko himself. For me 'Bosko and Bruno' was merely decent. Not great, but not average or less.
Its weak link is the story, which is paper thin, routine and at times repetitive. Bosko is still a fairly limited character, with his charm but not one who is funny or interesting in personality.
Bruno his dog though is far funnier, more interesting and more appealing personality-wise. His material is stronger too.
There are other strengths with 'Bosko and Bruno' too. It is well-animated, not exactly refined in places 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.
Regarding the gags, they are a lot of fun, there is plenty and most make one laugh out loud, inventive visually and they also have the necessary thrill factor.
All in all, a good but not great Bosko cartoon, around high middle as far as his cartoons go. 7/10 Bethany Cox
