My 5 year old spent the whole time laughing. We have the expression "grow up!" that we tell kids. Sometimes I think we need the opposite expression for adults who are peeved when cartoons don't make them laugh.
To me, this seems to be an expectations issue. I thought it was going to suck. It's a live action and cartoon mix about looney tunes, itself a broad and very meh cultural artifact IMO. Compared to my expectations, it was funny and good. It seems that you had very high expectations for it to "elevate the genre", which ... I struggle to understand why.
