There's no mention on who the director/ lead actor Hitoshi Matsumoto is in the other reviews, which may help prospective viewers to decide if they want to see this unique film or not. Matsumoto is one half of the arguably most famous Japanese comedy duo 'Downtown'. Their style is called 'manzai', that is one guy says a lot of stupid stuff and the other butts in all the time to correct him; you may have seen this in the background of some films by Kitano, who started his career in 'manzai' as well.
If you know that type of comedy, the otherwise completely non-sequitur style of 'Symbol' won't necessarily come as such a surprise, because the whole idea of 'manzai' is to baffle the audience by pushing nonsense as far as it can go. Since Matsumoto's part is the 'boke' AKA nitwit, it's pretty much in his line to come up with the most far-fetched, senseless and weirdest story angles imaginable - after all he's been doing this on TV since 1983! The ridiculous wig he's wearing in the film is actually part of his TV antics - I remember him wobbling around with it whenever he got an idea, pretty much like what he's doing here.
What surprised me though is that 'Symbol' has excellent production values, unlike his debut 'Big Man Japan' which suffered from very bad CGI (which may have been on purpose though). Here the visuals look so well done that I can't help but wonder about the budget. Another surprise unmentioned in the other reviews: there's an appearance by 'Kiss'! Other than that, I can only confirm what everyone else said: you may love it, you may hate it, that depends on how much you can forget about any expectations you have.
