Bubblegum Crisis Tokyo 2040, as well as Bubblegum Crash. The original BGC is a classic, but crash is brain so brain meltingly bad that many say that it doesn't even exist, and don't get me started on 2040!!!
then there's Gundam SEED Destiny, as said before, it was all unnecessary.
then there's also Eiken...oh god Eiken...I have to question why Media Blasters licensed this ALONG with all 18 (!) Volumes of the Manga, Ay-yayai!!!
I'd also Like to Mention Queen's Blade. and you can find plenty of hate for that over at Myanimelist.net
