I don't know who greenlit this supposed celebration of TAS, but the writing is cheap, lowbrow and cringey. It's a total shame that the amazing animation and sound design are paired with this quality of writing. None of the three eps released so far impressed me.
I'm seriously shocked by the Youtube comments that found it funny. The latest one is literally supposed to be funny because it involves boogers. Paramount should be ashamed it spent money on this. Have they stopped for a moment to think if this is what TAS fans want? /rant
I've seen some good reviews of the first couple - I think you have to be into a very specific type of Adult Swim-type humour that was in style about 15 years ago - but the only review I've seen of the latest one was not positive (and this was from a reviewer who quite enjoyed last week's instalment).
But whatever, they're ultimately inconsequential, having been described by Paramount from the very start as "promotional shorts".
