Personally, I am satisfied with everything as it is, since there is absolutely no difference between having 8 consecutive episodes about a common plot, and completely the same episodes but combined in a film format for about an hour and a half, and since we have never had films, and have never practiced such a format in principle, I think that the creators and writers would hardly have gone for such a thing. Mini-series for that and mini to remain series, but also to tell a story that is included in the general cycle of the season in which there is a mini-series, and the format of films would only on the contrary deprive and separate the mini-series from the general series.
