All of it is good, but at this point both 4400 and Kyle XY have enormous backstories. Psych and Burn Notice are both fluffy fun, in different ways (Psych is about a fake psychic who solves crime by extreme attention to detail; Burn Notice is about an ex-spy) and neither requires much investment. I suspect you'd like Burn Notice better than Psych.

I actually think you'd like "Mad Men" best of all of these, if you like period drama, but I have to warn you, it's quite depressing. On the other hand, it has Vincent Kartheiser, who I know you like.
