I've only watched season 2/Case 2 because of my love for Anthony LaPaglia, but, regardless of his excellent acting, I was pleasantly surprised! The acting all around is excellent, with each character establishing a strong hold with each storyline.
I personally adored the Jimmy/Justine relationship. It has all the same componants to Jack/Samantha in Without A Trace, which is awesome!
The storylines are exciting stuff, with the actual way of shooting ahead of its time, with all the earmarks of the current 24.
Awesome watching! I recommend it to any ALP, or law drama fan.
