The Bosko cartoons by Looney Tunes were hardly the sarcastic and edgy cartoons Looney Tunes came to be in the 1940s and 50s. Instead, the stories were minimal and consisted of lots of dancing, cutesy characters and not a lot of definition of our hero's character. When seen today, the cartoons seem very dated and, above all, aren't much fun to watch because there just aren't a lot of laughs.
Here in "Ain't Nature Grand!", Bosko has even less to do than usual. Most of the cartoon he stands around watching animals in the wild sing and dance....and he occasionally does the same. The closest to edginess it got was when some bees decided to attack Bosko but, sadly, by the end he was okay.
Apart from some decent animation for the early 1930s, there isn't a lot to recommend this cartoon. Yes, it is a cartoon...but it's lightyears from the sort of stuff the studio would make a few years later. Worth seeing it you enjoy animation history but otherwise, pretty sappy and forgettable...even for Bosko.
