I only saw a handful of episodes of Sarah Connor Chronicles and it never really grabbed me. I was never really able to fully grasp the thread of the plot, and part of it may have been that I was stupid or not paying close enough attention, but I kept getting the impression the show was expecting me to recall a bunch of trivia from decades old movies in order to understand why certain characters and events were important. And here I mean beyond just a basic understanding of who John and Sara Connor are, ir what Skynet is.
Summer Glau’s performance was probably the only thing that left a real positive impression on me from the whole thing; and even that was a bit of a novelty act. I know the show has its fans however, so it may just not have clicked with me.
In the realm of shows inspired but not actually based on movies, the recent Fargo series was quite a bit better than it really should have been.
