Well, the 60's Batman movie was pretty much just a bigger version of the tv show episodes.
I've found that if it's a new movie based on the books (reboots are the same) then it should be fairly faithful just to get the characters somewhere recognizable to other incarnations. For the Punisher movies you can't just have him running around playing Batman, leaving crooks tied up for the cops or a Punisher-mobile with him going home to his family at the end of the night.
How the did the Thomas Jane version was fairly well done. It wasn't the greatest but it wasn't half bad either. War zone on the other hand tried to go full on over the top murder machine punisher.
