Season Five is one of the weakest seasons of the show for me, really only a few a handful of episodes I really love. So, I'll be waiting for a discounted price instead of pre-ordering on this one.
Yeah, it's definitely weaker than three, four and six. There are still some great episodes, but on the whole it felt like a step down. And Worf's hair was absolutely atrocious throughout.
I'll probably still pre-order it, because I'm a sucker.
