I rewatched the tv series last year, shame the films weren't included on the boxset as I think they're better, certainly a lot creepier.
I think the show is ok, too formulaic and not nearly scary enough (although it does have its moments).
On the plus side Darren McGavin is always a joy to watch and I was really impressed that they actually managed to come up with some really inventive monsters of the week, they must have trawled the myths of dozens of cutulres (some are really obscure) to get them.
Plus its fun to spot the guest stars (Huggy Bear, Jaws, Ponch from CHiPS etc etc)
The Prisoner is a fantastic show, I'm not sure why I don't own it on DVD!
