I watched “Heroes” last night while babysitting. After all these years of reading X-Men, I thought I had my ideas about ideal superpowers all figured out — definitely flight with some super-strength and a little shape-shifting when handy. But then I saw the “Heroes” character who can mimic whatever she sees and knew I’d found the right power for me. I would be a pretty useless mutant in battle, though. Because, if I were her, I would have stopped watching Bruce Lee movies in about two minutes, switched to Country Music Television, and bought a guitar a.s.a.p. Then started watching PBS orchestra specials and Discovery’s “Man vs. Wild.”
