it depends on what show and movie, there are pretty good shows in tv and there are pretty good movies too. I think both of them are good it will just depend on what you prefer more watching.
abit of both, some films wouldnt suit series and so on. Series i like as you can always look forward to the next episode.
if I can count old TV shows I replay on DVD/computer, then I'd say TV shows. I say this as I re-watch the black adder complete collection for the 6th or 7th time perhaps. Can't live without it.
TV shows. most people are very much fun of Reality TV like American Idols, Survivors, Amazing Race and etc..
