It's funny & imaginative, as everyone else has mentioned. However almost no-one else has mentioned that the film was intensely satirical when it came out - practically everything in it captured the zeitgeist in London at the start of the 80s, from the flapping sacking around office buildings being refurbished to the wholesale layoffs/business closures. Maybe irrelevant to the casual viewer but IMO it's the most political Gilliam film that I've seen. Incidentally I believe that the building used in the exterior shots is Loundes House - still standing just north of Finsbury Square in the City of London.
