Quoted for emphasis. Most of the guys I knew who did JROTC weren't troubled at all. Whether it's worth doing all depends on the instructor and your interest in the stuff you'll be doing.
There's no harm in trying it, since it doesn't bind you to joining up or even continuing through your entire high school career.
I probably would have done it, but my school didn't have it on offer. My uni didn't have normal ROTC on offer, since it was OCONUS. Still, no regrets here about taking the enlisted route, as it gave me a few more options when it came to contract. RLTW!
