I became a fan in late 80s by reading comics. There, Batman was a loner without Robin and was solving different crimes and mysteries in each issue, all very dark and sometimes even spooky. So this is MY Batman. Months after I became a fan the 89 movie came out and naturally it was even darker in tone and design than comic books, so naturally my preference goes to lone, dark Batman
But having said that, I enjoy the 60s show as well. I guess it just depends whats fun and what appealing to me. While I enjoy the 60s show, I dislike the Brave and Bold cartoon and Schumacher's movies
