Well with what I actually finished it would definitely be
No. 6. . I knew the sci-fi aspect was going to be rushed so I wasn't expecting much from that (although I also didn't expect it to be as bad as it was in the end). However I actually hoped the relationship aspect would make up for the rushed plot. Unfortunately that was not to be the case and I felt they even messed that up in the end.
But really the most disappointing thing about anime in 2011 was the "big" announcement of what the new
Rurouni Kenshin project was going to be.
