Hannah barabara stuff is shit. Not even that it didn't age well if I wasn't a child when I first watched those I'm sure I wouldn't have liked them at all. I tried watching Catch the Pigeon and Topcat recently and couldn't make it through a single episode of either they were so fucking dull. Literally none of the jokes even made me smile everything in it was just dull and boring, I couldn't even enjoy it from a trainwreck perspective as it didn't make me angry or anything, just dull as fuck. Also graphically they look shit as compared to newer cartoons using flash and the like. Cheaper flash like in MLP is so much better than the expensive old drawn style. It just plain is in every way.
I made a point of NOT watching Wacky Racers since I remembered loving that show as a child....and to be honest, I want to leave that obviously nostalgia blinded childhood memory in my mind and not look at how shit it is like Topcat and Catch the Pigeon evidently are.
As for black and white cartoons I haven't seen any outside of "tributes" of them which are shit, and so I don't watch them, since if the tributes in games and the like (the black and white section of Kingdom Hearts 2 as an example) is shit with newer technology and humour I dread to think what the actual things were like.
As for Loony Tunes, I don't like the older stuff, I can watch Road Runner that is solid and also I love Tom and Jerry and Rugrats but outside of those my cartoons need to be the newer shit from the flash age. So much more appealing and funny. Like I loved Taz and the like in his nice 90's show and love some of the Loony Tunes games like Taz-Wanted, but Bugs Bunny cartoons fuck that shit, him and the duck and the woodpecker and the like just seem boring to me. Sylvester and Tweety are good but only from their respective Sylvester and Tweety Mysteries show I watched which again, was 90's.
Not to say all cartoons in the 90's were good, like The Adventures of Sonic the Hedgehog was pure gold but Sonic Underground made me cringe even when a child. Sonic SatAM seemed decent but fuck that ever being aired in England I remember seeing like 3 episodes.
