Yeah there's Channel 101 all over this.
It's funny you say that cause it's the total opposite for me. I felt the same way about Community, didn't watch it for years, and as of last week finally gave it another shot and now I absolutely ADORE it and have been burning through the seasons. Rick & Morty, however, I hate because it really really really tries too fucking hard.
Well, let me rephrase that. I hated the Channel 101 shorts, because they were 100% shock value humor and gross out gags. The new show I've avoided because of that, but when I saw Harmon's name attached and with my renewed love of Community, I decided to give it a shot. I've only seen the Meeseeks episode, which I actually DID enjoy, but the show relies ENTIRELY on characters screaming their lines. "Yelling your joke doesn't make it funnier" or whatever the phrase is. As much as I enjoyed it I found it grating and almost anxiety inducing to sit through 20 minutes of constant shouting. It's like someone took Lemongrab from Adventure Time and made him every character (literally, as he's the same voice actor as Mr Meeseeks). To me, that's really trying too hard to be funny.
It sucks [for me] because for the most part, the writing IS good and what I've seen of the show IS funny, and I want to watch it from the beginning since there's apparently a continuing narrative, but the reliance on the screaming and yelling might kill it for me.
