As I say I prefer TV series. Why? In the movie I don't have enough time to get to know a characters. In TV series i have much more time on get know about the plot and characters. Also in movie I just feel bad, when I stard watch and I start thinking that it's only I don't know. Two hours? It's not enough for me. The exceptions are film sagas. Howewer for me the best are TV series with many seasons, or with many episodes.
