I'm thrilled with this news. I'm still a big fan of Alias, and I liked the new Star Trek movie, too.
As to Joss Whedon, I'm actually not a big fan of his stuff. Avengers reminded me why he could be good, but I didn't like how he ended Buffy, Angel, and Serenity. Seems to me like he runs out of steam before he finishes stuff. Both Buffy and Angel should have been at least one season, possibly two shorter.
