I forgot about Harper's Island, yeah, it was too dark for me too. Not my cup of tea at all.

Covert Affairs was really good in the early seasons, I gave up on it this most recent one. It was on as the same time as something else and I meant to catch up and watch the episodes later and I just never cared enough to bother.

I have a lot of respect for Christopher though, his character on Covert Affairs is blind (due to a special forces combat injury) and he's done (and continues to do) a LOT of work to make sure he portrays the character accurately and uses his fame to raise money and awareness for a lot of blind/wounded vet causes.
