Don't expect old-school Warner Bros. here because you won't get it. However, Looney Tunes Show is actually... entertaining. Imagine Seinfeld meets Bugs Bunny and you have the basic idea.
The humor doesn't come from zany hijinks or slapstick comedy (although there are a few here and there) but from seeing Bugs, Daffy, and everyone else in a number of trope-heavy sitcom scenarios. Two "friends" on a game show? Yep. High school reunion? That too.
It's very much hit or miss depending on your idea of comedy but it definitely puts a brand new spin on Looney Tunes while still having plenty of funny, absurd moments.
