Well, we have only watched season 1 and 2 so far but regarding action we liked episode 5 of season 2, Nikki and Daniel from Dallas. We found them both hot to look at, although Nikki was a bit too pushy and Daniel was or acted shy.
What ever you do, don't choose season 1, episode 4 (Mark and (another) Nikki) unless you want to see full unreasonable drama with lots of yelling. We could not finish watching that wreck.
