i tapped out from ghosts us in season 3 ish. saw maybe one or two part episodes since
i dont think i missed much.
i would say us and uk shows are on par with each other, but the uk series knew when to hang up the hat.
and lets face it you can really milk a popular show in the usa for a decade if it costs little to make.
most of what i saw in the usa show was the uk episodes redone, and most were redone well.
(seriously including a viking is the usa was just desperate writing, and that is the best that can be said for that)
granted the usa has a much shorter history to work with, they definitionally glossed over a lot with their choice
of ghosts on both shows.
the actors are all about on par and do a good job for the lines they are given.
its a pretty good comedy show compared to much of the competition,
but not a show that is getting better, or really has any where to go.
and in the usa you can get a LOT WORSE and still be on the air
