Liked it. Invasion definitely has potential. The opening hurricane scence might be a little too much deja vu for some people, but I give Shuan Cassidy kudoos for writting a wonderful premiere episode. Invasion and Threshold are the best out of the three that premiered but I think Threshold may have a harder time getting a audience as they are really going for the intellectual audience (think Lost/X files fan base) and they just may not be there on a Friday night. Surface is hooky sheer fun and may not last more then 2 or 3 seasons (the appeal of Lake Bell, the main heroine, may not last more then 2 or 3 episodes before she totally annoys me) before it runs out of steam. Invasion seems to have a good balance of both and will probably appeal to a wider audience.
Great casting for the daughter, loved the cat, very laid back.
