Off the top of my head:
>Samurai Jack Last Season
Started strong, ended abruptly and a bit cheaply. Was good overall, 7/10.
>Code Lyoko: Evolution
Complete and total dumpster fire. I only watched 30 seconds of it and all the decisions were fucking retarded. Please note: it is not a remake, it is a continuation that decided that an animated show should become half live-action. Bankrupted the company making it. 1/10
>Mushishi Second season
I haven't watched all of it, but from what I saw, it was mostly good. It feels like it lost a little bit of charm from the original, which made me drop it momentarily, but from what I watched, solid 7/10
>Family Guy
Well... it's Family Guy. I can't say it's good, but if you like Family Guy, you got more Family Guy. You got a LOT more Family Guy. Technically it was only a 2 year gap, but Family Guy was cancelled, then revived years later. Massive financial success. 4/10
>GunBuster 2
I don't know about this one, technically it's a continuation, but stylistically and content-wise it might as well be an entirely different show. I like the original better, because Anno is a fantastic animator, but this is Imashi's baby so that Gurran Lagann could be made. 6/10
>Digimon Tri
15 years after the end of the Digimon 2, we got another season. I haven't watched it, but it's apparently financially successful and the Japanese love it. Please note this is a direct continuation of the first two series, not Tamers, or the train one, or the punching digimon one, or the smartphone one. Unrated/10
>Berserk continuation
Complete dumpster fire animation wise. 2/10
There's probably other stuff. I'd mostly say it doesn't look like it catastrophically fails most of the time, it's just kind of boring.
