There is only so many times you can watch a given film or program and I find like I dare say many others that as you get older more and more are just repeats and even with the newer offerings you soon see the underlying theme is a rehash of something that has gone before because there are only so many themes you can have, a bit like having the same film and just changing all the names and the location.
The one thing that I find totally ruins any film is when they become completely unrealistic, you can get away with this in sci-fi but not in films like bond which is probably my most disliked of all and in films where you have some shoot out with hundreds of rounds flying around that all seem to miss so many people apart from the extras, I think we are tuned into reality unless you are an avid gamer.
