Billy Jack 1971 and Billy Jack 2004

I just got thru watching all 4 of the Billy Jack films, I know a lot of critics are down on the films for the contradicting peace by means of violence, but characters relate to each other in the films in an ad lib fashion, such as real life, what would be called bad acting is more or less the way the characters relate to each other, the films have a script, but as Tom Laughlin points out with his wife Delores on the commentary tracks, the script is more like a guideline, the rest he states comes from inside spontaneous and raw......Now there is a rumor on the net about a possible remake with Keanu Reeves in the title role, just like there is a remake for Walking Tall in the process with the ROCK considered for the title role.....any comments would be welcomed.....and just 3 more days till DIOE ANOTHER DAY and SERGIO LEONE'S ONCE UPON A TIME IN THE WEST....THANKS
