I don't think you can compare Rose and Amy... they're just different. I like them both. I'm also happy to say that I was skeptical of both Matt Smith and Karen Gillan going into this season, and both have done a great job
The finale was very good... a few disappointing holdovers from RTD, but nothing to keep me from enjoying it. It's nice to see that there will apparently be a multi-season story arc in discovering who was behind the Tardis explosion
