Really good but really hard to understand the thick Scottish accents. The dvd I watched didn't have a subtitles option so my house mate who had seen it before had to summarize for me what they were saying in some scenes.
I was lucky enough to get a ticket to apparently the only 70 mil screening in Australia. The plot points can be a bit hard to keep up with at times but that kind of matches the protagonists pot fueled mind. Anyway it wouldn't be a PTA film if it didn't encourage re-watching.
