Hmm, just found this at TV Tome.

This is the first time J.J. Abrams has not written the season finale.
J.J. Abrams apparently rewrote the script alot because he didn't feel that the original had everything that he wanted.
Maybe that is why this one just seemed...meh. No big suprise or anything. The Katya betrayal didn't make much sense, Lauren will probably be back, Sark is in custody (again), Sloane and Nadia are off to find Rambaldi's essence or whatever, nothing more revealed about the Covenant, and Sydney finds out what? Just too much left unanswered when they could've tied up some loose ends and set up new ones. They're writers, shouldn't be too hard.
