Finished the premiere this morning. Not bad. I liked the twist at the end with the male agent double-crossing. The characters show some promise. I'm not totally sold on Joshua Jackson's character. I've never really bought into the predictable Hollywood archetype these supposed genius characters are given. Kind of the same thing with his dad. The whole "I'm just so friggen smart that my behaviour is off the wall crazy" bit has been done too often. I'm sure that his acting ability will make it enjoyable enough in the end though.
They do explain later why Walter is crazy.
