The problem was Martha was written really we except for her Rose-carry-over storyline of craving after the Doctor, which seemed to come out of left field sometime near Gridlock. Her unrequited love speech at the end of her travels was lame as it was clear the Doctor wasn't interested in rebound sex (what a pillock), and it should been dropped. Having companions wanting to shag the Doctor was a very RTD thing, and at least Moffat had the idea of bringing Rory in to divert that. Martha was probably my favourite companion of the new era but the love arc just ruined it.
He was as pig ignorant about her feelings as she was about his. The unrequited love speech was "This is why I am leaving you great big muppet" more so than "last chance dude, please, please, please."
On the plus side it was the right planet, and the right country on that planet and the correct time period. Given the noted unrealiablity of the TARDIS to take him where he wants to go, I say he did well.
