U, PG, 12A, 15 and 18; it's a hotly debated topic at my work (I do more than one thing but cleaning my local cinema is an essential part of my income), and I've no idea what the public makes of it. U is obvious, a U movie is deemed suitable for a child of four. PG, well I bust the rules slightly and took my daughter when she was four to Jurassic Park, PG is considered safe viewing for 8 and over, as did many others. No problems and I think most...
