I am an extended edition buff and have a big collection of original ones and all the fanedits from here.
Many extended editions do not add anything to the movie, just add more useless scenes. I will rate the ones here.
Rating criteria: image quality, sound quality, 3x improvement, overall.
Image Quality: 10 of 10
Sound Quality: 10 of 10
Improvement: 5 of 10
Overall: 7 of 10
Life of Brian is a great movie so making it extended was for me a great idea. Unfortunately, the quality of the added scenes are not as good as the rest of the movie.
However, this new scenes are funny to watch and they were removed just because the did not add anything to the main plot. Overall, I think that if you like this movie you will enjoy this Extended Edition.
