Aw, I was worried about how the numbering worked. So, what I call Season 6 is the second Matt Smith season. I don't consider the set of specials that ended Tennat's run ("Planet of the Dead", "Waters of Mars", and "The End of Time") to be a separate season, because each were just long episodes.
So basically, I've seen all of the current Doctor Who. And yes, I loved the latest season. It was fantastic. I really liked how this season's finale took a departure from the last few, where it wasn't trying to pull at heartstrings. It was mostly a really funny romp, and I loved that. Matt Smith is at his best when the Doctor is just being goofy and weird.
