A truly great movie though, which criss- crosses through genre's of psychological thriller, science fiction, tragedy and action.
This is a movie that expects you to pay attention and make connections. Leonardo DiCaprio gives a heartbreaking performance, leading a cast of top-notch actors playing interesting characters in a film that appears to be a science-fiction action/heist caper (a rather unique concept in itself), but is actually about guilt, the desire for redemption, and the raw power of simple ideas. Director Christopher Nolan, as he did with Batman Begins and The Dark Knight, takes something fantastic and paints it in realistic tones. This is what unbridled imagination, combined with intelligence, emotion, and talent looks like on film. It is mentally and emotionally challenging. It also has some terrific action (including a physics-bending fight sequence that is jaw-dropping) and is very creative in its use of cinematography, editing, and music. Though comparatively light on language, with no sexual material and action violence where physical harm is not what's at stake (you'll understand when you see it), Inception is nonetheless not recommended for anyone younger than teens due to its complexity and intense subject matter.
