I can't watch Beast Wars any more, that computer animation has not aged well. I also don't think the Samurai Jack animation has aged all that well either, I much prefer Tartakovsky's other works like the Star Wars animated show and Sym-Bionic Titan.

In terms of others on your list, Batman Beyond is one of my favourite shows ever, something about superheroes and high schools does it for me, especially when it's set in a Blade Runnereque future.

For the life of me, I can't remember if I ever saw the ending. Was it Reboot ending bad?

Well honestly I don't think they could sustain that level of animation for a series that had little coverage outside of Europe. I'm not sure how it did in the US. I doubt its a household name to say the least.

And yet I feel that show still has more life than TF: Prime. Seriously, Prime feels devoid of character and/or personality to me.

I'm not sure if I should spoil. even if the show is a old and sorta obscure by now. :lol

Shall Youtube marathon it then. Thanks.

For me, my favorites are:

1. Beast Wars: Transformers
2. Avatar: The Last Airbender
3. Batman Beyond
4. My Little Pony: Friendship is Magic
5. Young Justice
6. Static Shock
7. Teen Titans
8. Spectacular Spider-Man
9. TMNT (2012)
10. Transformers Animated

Some of my faves have always been

King Arther and The Knights of Justice

Beast Wars's animation has NOT aged well.
However, it's a good case of letting it's story carry it, not it's budget. While the slapstick of S1 wears thin, S2 and 3 (S2 more so) are still really good.

That's a fair assessment.

Oh man, how could I forget about Gravity Falls?!
That show's awesome!

I cannot believe I had forgotten this show. I really liked it when I was younger!
