The thing with Looney Tunes is that they're an animation showcase. They rely heavily on visual gags. Script wise, they don't offer much beyond characters trying to eat each other. From a POV of a gag-animation connosseur, Looney Tunes are the "bee's knees". Much of the sophistication of these cartoons come from a visual standpoint, and understanding these gags sometimes requires a bit of life experience.
I will say that as a kid, I was not a big fan of LT. I watched them, but I was more into Tom and Jerry and The Pink Panther. For me, The Pink Panther basically was all mood and of course the music, which I used to hum all the time. Tom and Jerry satiates the inner sadist of every child.:evil: But LT is probably a little more sophisticated than that, which is why they've often always been more for gag animation fans.
