And,, the movie came after HL2, so valve could have been reading the book?
Don't you know of the radio series that aired in 1938? it was before people had normal acess to television, and they didnt announce that it was a story so people beleived it, rioted and committed suicide. it was horrible...
as for book that was written in the 1870s, it was set in britian so what did Holywood do? Set in in America of course to prevent copyright infringment.
The ending was bollocks. They obviously didnt have enough money to destroy Boston or use any more special effects there so they decided to end the film there wheras in the book, the main character is seperated from his son and daughter and dies a lonely, sad man.
{On top of all that, it had Tom Cruise in it which makes any film crap}
