Query: Could have been alot better.

I don't recomend you to buy this movie,because it's not nearly as great as i thought it would have been..The plot it's about a man named David Dunnes(played by Bruce Willis) that survived on a train accident and didn't suffered even one scratch,he's a security guard and he's too strong even for a human been,he's sobrenatural and prodigious!besides that,he was the only survivant from the accident.He also meets a man called Elijah(played by Samuel L.Jackson) that it's the exact oppost of dunnes,he was born crippled,and will change David Dunne's life forever!As you can see,the plot offers something new,fresh and interesting,and the cast it's pretty good,featuring very well known stars such as Bruce Willis,Samuel L. Jackson and Robin Wright Penn.The director is also pretty good .A very good concept movie,but very frankly,the results could have been better.I didn't even see all the movie.
