I stopped DVRing Five-0 and really don't miss it.
I mean, it's entertaining in a popcorn kind of way, but I don't feel like I'm missing anything. Should I try to catch up?
I think it's better this season--the cases are still pretty outlandish, but the character stuff has been better, and they've been playing up the bromance, which is my favorite part of it. I loved the episode that delved into Danny's back story, too.
I feel like everyone has one or two popcorn shows on their DVR, so I guess it comes down to whether you enjoy it enough to make room on your DVR for it.
