I used to think Life of Brian was unquestionably the best of the films, and I didn't think much of Holy Grail. Oh how times have changed!
I still really like LoB, but I really really really like Holy Grail. A lot! Much as TechnoTim does! Unfortunately I have got an affected player, but the subtitles aren't too distracting.
Haven't seen much of Meaning of Life, although what I have seen looked hilarious, only not as much as the others.
