It feels like Ren & Stimpy sometimes because one of the writers (Katie Rice) did work on the Ren & Stimpy reboot! So you’re spot on with picking up on that. IMO that adds to it rather than detracts because so much of R&S was making references to or riffing off the ‘golden age’ of cartoons that Looney Tunes was part of, but if that style of humor is boring to you then I could see it detracting from the movie. I wasn’t constantly cracking up or anything, but I was smiling and laughing more than I was bored. Which honestly feels like a huge hurdle for movies now, lol.
