The story line and acting was what got me there.. The acting lived up to my expectations - which were high considering the wonderful cast. The story was also good, but ran out of steam and left me a bit flat. Mark Ruffalos character was too cliche, which detracted from the authenticity of the movie.
Action packed, a little bit of everything.. bit scary, often corny, highly improbable, occaisionally sad. Great special effects and acting. Highly entertaining.. Mind candy..
