Bosko is a Mountie and has been sent to get his man. The baddie, it turns out, is clearly modeled after Disney's Pete (from "Steamboat Willie" and other early cartoons). Along the way, there is some singing and dancing--though what this has to do with the Mounties is beyond me!
I have never been a fan of the Bosko cartoons. They were heavy with the schmaltz--lots of overly cutesy singing and dancing and mugging for the audience. Edgy, they were NOT! Now I cannot blame Warner Brothers alone for this--many of the rival studios such as Van Beuren, MGM and Terry Toons were incredibly insipid throughout the 1930s. Cartoons we know and love today (such as MGM's Tom and Jerry and the Looney Tunes crowd) were all cartoons of the 40s--after the happy, singing, cutesy fad had, thankfully, faded. So, in light of this, my score of 5 for "Big Man from the North" is actually very positive--and I was shocked that I didn't hate this short!
