It embraces its own cheesiness so well.
I makes me laugh that the ex-IRA girlfriend couldn't do an Irish accent and actually stopped even trying after the first episode. I love that the main actor belongs to the Keanu Reeves school of acting (ie don't act, just say the lines as though it was a read-through). I find his mouth and teeth almost hypnotic, he has a very odd shaped jaw. I particularly love the Mcgyver-style cobbling together of high-tech from components available on the high street. It's also a real pleasure to see Cagney (or is it Lacey?) back on the the tv.
I guess the charm will wear off unless they actually manage to come up with a plot, but so far I'm enjoying it.
Anyone else?
