Thoughts, in no particular order:
1) Martha is really in control, where as with Rose it's just an average day until the Doctor comes in. Nice she is a major control force (like billie at the end of the last series), but is going to be interesting to what will happen when she has gone from the family.
2) Thought the bit in the beginning where the came in was weird, but maked sense later on.
3) Woah, so cool effects! Although slightly "Aaaah I am falling in a room.." weirdness
4) I was thinking Bubble as well.
5) Judoon are cool!

Nice to see tough bureaucracy once in a while!
6) Oooh Weird X marks..... Purdy...
7) Thought the lady was getting weird when she went into the dudes office...
8) Hey look the Stig got a role in Doctor Who!
9) Lots of action here! Non stop stuff!
10) Random Kiss Scene... Nice to see some random explanation this time round...
11) Was thinking that letter her suck his blood was the solution
12) Ood purdy machine.. Surely that would run the generator down quite quickly?
13) I was expecting the Doctor to fart the radiation out...
14) Was thinking "Where is "Mr Saxon", oh probably on the radio".. LOL
15) Weird scene, setting up for a triology, when she gets back they have searched for her... Seen it before!
16) Weird thing is, Freema knew she had the job of replacing Billie
before we even knew she was leaving!!! Probably means that they have DT's replacement sorted.
That's about it I think.

All in all a good start to the series, and I really like the new assistant. I say..... 7/10?
