Angel season 5
I just skipped right to it. It's amazing at how well it works as a standalone, at least in the early eps where I'm at (they explain what needs to be explained). I'm pleasantly surprised at how much I'm enjoying it. I thought I'd skip over a lot, but so far I haven't done that at all! (I probably will in some later eps.)
And I'm reminded how I got to appreciate Spike again, and how Fred became my favorite character (while I liked her before, she was at the bottom of the list for liked characters until she defied Jasmine, and then in season 5 she rose to the top of the list and stayed there).
I expect season 5 was a lot more fun to write for and act in than earlier seasons.
