Similar comedy style and length, bursts of hilarious moments throughout each episode of each series.
Very similar fast paced and random style of humor. Both have short episode lengths and are easy and fun to watch
Similar style and type of humour, even though DMC is more fast paced and has less original content (ie. ammount of jokes)
Both series have a similar kind of random, quirky, unconventional humour, a similar aesthetic style, character who are supposed to be rough and tough but really aren't (a death metal band who've done nothing to deserve their infamy, the world's most well-behaved delinquents), and short episodes to boot.
As you wacth one, you will remember the other. The humor on both is so similar. You will catch your self laughing out loud with DMC if you lol'd with Cormartie, and vice-versa. I would'nt say that they both have equal art style, but surely, they both distinguish from generic look.
Same type of crude humor and similar styles. Also very fast-paced. Short episodes that'll made you lol. The main characters try to be rough and tough, which they really aren't.
Both Cromartie High School and Detroit Metal City feature mild, unassuming protagonists who are thrust into the company of crude and crass individuals. Cromartie and DMC both feature offbeat, wacky, and often abrupt humor, and both series follow a similar "half-episode" format.
Both have a unique style of humor, unique characters, are fast paced (which is nice) and are god damn hilarious!
Similar type of humor. Ridiculous and fast-paced comedy in a "rough" setting (school full of badasses and death metal industry).
Simmilar animation, comedy style. Both have hilarious gags and some randomness.
Both series involve a timid, normal main character thrown into a ridiculous situation. Both use similar styles of humor and have cheap animation. If you like one series, it is pretty much guaranteed you will like the other.
