My wife and I (ages 30 and 37 respectively) really enjoy this updated take on the Looney Tunes characters. If you haven't watched this, here's a short description for you. Daffy moves in with Bugs and it's a very much like the Kramer/Seinfeld relationship in my opinion. Daffy causes various outrageous situations and Bugs has to clean them up or suffer through them. Other LT favorites are here as well, Yosemite Sam is their neighbor, as is Granny, who owns Sylvester and Tweety. There are Roadrunner Coyote shorts which are very much like the old ones, just with newer 3D-ish looking animation. To be honest I like the old ones better, but the new ones are good too. Speedy Gonzales owns a pizza restaurant for some reason. Porky is a loveable loser. Lola Bunny is a great new character as a crazy stalker obsessed with Bugs. Elmer Fudd is a newscaster.
The humor is really more for adults than kids, as it is sometimes quite subtle, for example Daffy Duck gets some "business" cards printed that simply say "Daffy Duck - Wizard" This new version of the show is more plot based than just the random silliness of the older cartoons and centers on situations like Daffy Duck's high school reunion or Bugs making a TV commercial for Speedy's pizza place. So I think this show is for sure made for grown-ups who enjoyed the old version growing up.
Each show also has a short musical part in the middle called "merrie melodies" which are always good and sometimes very hilarious and creative, like Foghorn Leghorn singing a "Cock of the Walk." Also, as with Seinfeld, there's a final short scene that acts as a coda for the entire episode.
As someone who grew up loving the original Looney Tunes, and as someone who enjoys other more edgy animation (Simpsons, Futurama, some older Adult Swim stuff, etc.) I would recommend this show.
