Agreed about Rose's jealousy.

On Rose and Mickey get along really well - it felt a bit too quick after her pouting at the end of last time. Given what I remember happening over the course of the remaining episodes, they should have done a bit more to cement Mickey's place on the team, rather than it feeling like he's just there for a little bit. That Cleopatra episode sounds like it would make a nice story of its own.

Doctor as the "Romantic Hero" does work well. On the actual romance itself, I tried to ignore the whole "I met you as a 10-year old just as many minutes ago".
