Not really sure why it was so panned by others - yes it was not great but it was OK - story and characters seen a hundred times before, a few double takes on the script/plot but what the hell I have seen way worse movies with multi-million dollar budgets with much bigger holes in the plot, worse acting, worse lines - you name it.
Overall - same sort of plot/quality etc as the punisher/dark man (yes I know DM is a bit scifi but it is still essentially the same movie) both of which managed to gain over 6 ratings on imdb so really not sure why this was disliked so much - those two were much the same and even got follow up movies/TV series as well!
