Being a fan of Tom and Jerry growing up, I was a bit nervous at the new "Tom and Jerry Show" (not to be confused with the old MGM one), since it was very obviously done in flash animation, and I admit to having a lot of the prejudices that I hate seeing in other people (don't worry, I find it stupid that I have them, too.)
Animation style aside... this is Tom and Jerry at its finest. The 2010 series had great animation, but didn't quite have that Tom and Jerry spark. This... may not have the best animation (though it grows on you surprisingly quickly) but damn it has that spark and more.
Also it's nice to see that Jerry's no longer karma invincible. Both Tom and Jerry hurt themselves almost as often as they hurt each other, through their own plans going awry. And Spike is no longer blind to Jerry's antics - there are two episodes where he targets Jerry just as much as Tom.
That's not to say I'm a Tom and Jerry connoisseur, but it's something amusing to watch, and it definitely brings back a lot of nostalgia, in a good way.
