Third series was the worst
Overall I thought "Robin of Sherwood" was a fun if mediocre series, it wasn't bad and the cast for the regular cast for the most part were first rate (Nicholas Grace was good but went a liile too OTT sometimes as Nottingham). That said it could be too cheesy at times, subtlety sometimes went right out of the window and after Michael Praed left and Jason Connery took over it began to slowly go down hill although it wasn't entirely Connery's fault. I think they starting creating too many episodes with not enough writers onboard which didn't help matters, some episodes were too padded out (ie. the one where Will and Much think they have caught leprosy).
Connery, god bless him as much as I have heard that he's a really nice guy, he's not much in the way of the actor. He had no prescence or charisma in the role what so ever and was rather bland, particularly in comparison to Praed. He never really melded with the rest of the cast that his predecessor had and he had barely any chemistry with the actress(who's name escapes me for the moment)who played Marian.
