At the end I thought it was going to work as a miniseries, but as it is, I don't find any problem with it and after the premiere of the end of this story, I liked the three movies, now I don't know if they were going to work in the cinema as it seems they were originally going to be released.
These movies are not perfect or the best, I see them as a good tribute to the genre, very entertaining and with a lot of potential to make more movies.
