Agreed about something missing. I've enjoyed 2.0 because I like the new characters (though I also miss the old team terribly), but I really miss dark!Jane as well. I guess the writers felt a pressure to make the show more lighthearted again (I've read a lot of complaints from people who hated the darker, more RJ-focused seasons) and that's why they had Jane deal with his issues off-screen during the 2-year time skip. Which is a shame, because whatever happened during those two years would have been to me the most interesting bit.

Looks like we're in the minority, though, because reportedly "Blue Birds" is already the highest rated episode of the show on IMDb...
