The period directly after Chuck Jones took over was the END of the good Tom and Jerry shows. Even Chuck Jones was pushing it, with his new take on the characters, and his daring new, very art deco style, yet it was notably worse than the previous series. Tom and Jerry pre 60's was probably up there among the best cartoons ever made, it was timelessly funny, magnificently written, lovingly simple, charming, wonderfully and shamelessly violent, and had brilliant music.
I remember watching the modern Tom and Jerry shows, must of came out some time in the 00's. It was complete utter shit, even the children watching it knew how shit it was. I was disgusted with everything in it. The fucking voices, why have voices!? The animation techniques, why change it!? The music, don't even get me started... The new characters? What the fuck are you trying to do!? And each episode had a plot with a moral at the end, telling you to be good, share, don't be violent, make friends, not enemies... fuck that... If you want to preach about that sort of thing, don't use Tom and Jerry as a bloody vessel! They don't need it! There is no equal to the magnificence of the old Tom and Jerry.
Sadly, because of political correctness, and the 'protecting our youth whether we like it or not and if you don't comply we will call you racist, sexist and a freedom hating hippie act', no show will rise to take up Tom and Jerry's mantle... I can say that with complete honesty...
