Can you still enjoy a television show if you don't like the presenter hosting? I'm talking about programmes such as Autumn Watch Country File, chat shows, quiz shows, talent contests, etc. If the contents is good, but the host annoying, will you still watch it, or is their personality what makes the show?
It depends how prominent the host is. If they are on screen most of the time, then I think they are vital to the show's success; if they only pop up to make an announcement and move things along, then I can live with them being annoying.
The host is of vital importance as he/she is the driving force behind the program. Deal or no Deal, was for me a great show but the host (cannot remember his name and not sure if he still presents it) was a major turn off through irritatingly bad jokes/puns.
