Here are my 2 cents:
-The Anime flavor, I don't mind. Anime and Manga-type stuff has only gained in popularity over the years, and that's only to be expected: It's fun, it's expressive, it looks cool, etc. I myself am a fan of American Manga like Gold Digger and Ninja High School, and Jackie Chan Adventures (an anime-type series) is one of my favorite cartoons.
I honestly prefer american-made anime-styled shows over original japanese shows that were badly dubbed (4Kids, this is aimed at you

)
-The Animated Universe containing Animated Batman Animated Superman, JLA and the like, I prefer to think of as "Ultimate DC done right". They take classic characters, scrub off years of continuity, keep essential elements of personality, then add some modern popculture and pop them into a modern-day setting. They've saved the basic elements of the original Titans (Raven's Angst, Starfire's Innocence, Beast Boy's comic attitude and Cyborg's Anger) and gave them modern spins.
-I don't mind that Deathstroke is only called "Slade" in the cartoon. Some of the most bad-ass villains in cartoons and comics are known by a simple, short name: Doom; Kang; Luthor; Aku... I also like how he's more manipulative and organised, a master villain rather then just a mercenary.
So far, Teen Titans looks good and fun to me.
