I think they took cares to finally show the breaking point for certain characters towards the end. I knew Andy would eventually diverge from her sister who seems to be oblivious to the fact Sentinel Services is out to capture them, and I only wish Andy had unleashed his power on his own and we could've seen his rage fully manifest. His bitterness towards them makes for some excellent action and tension with his family, and I was cheering out loud when He joined the Hellfire/Brotherhood and I hope to see Polaris train him more and develop his power. The scenes with Polaris and her finally waking up were well done- I just feel like Eclipse really gave her much of a choice. Also the same thing with Blink who didn't really have much to do in the finale, but she has to be aware that you can only run for so long and believing in beatnik ideas is counterproductive- humans have shown no willingness to accept them.
Altogether I can't wait to see what happens between Eclipse and Lorna, and I want to see the Brotherhood destroy Sentinel services and see what anti-mutie schemes Turner has planned. Its going to be an intense and dramatic season 2
