Over at Fantasy Magazine:
Eliza Dushku has had the opportunity to dazzle us with the range of her acting over the course of this season. She did not. In this final episode she had one more chance to shine. She had a great example before her — Alan Tudyk as Alpha struggling with the different brains in his brain, switching smoothly between them without making it look hammy and overdone. Then he puts a ton of personalities into Echo’s head and Eliza gives us… well, the same vague “kick-ass chick” character she’s been playing for eleven previous episodes. It shouldn’t be a surprise that we never saw her switch between them. There was nothing to switch.
There’s… a lot more. It took me a whole week to write because every time I sat and thought about ti some more I was like, “Oh, and ALSO I hated this! And this!” Watch as I also compare the show to Family Guy and Heroes. Clicky for the fun!
