I understand the rating of 8+, but for our kids, 4 and 6, there is no better show. (The goofy special effects on some level negate the possibility of it really being too scary.) We like the show's positive messages, the questions the plots inspire, the friendship of Kirk, Spock, and McCoy, and the interest the kids are now showing in science. For kids, what's better than good stories involving spaceships, guys in monster suits, bright colors, and styrofoam rocks? Ultimately, Star Trek TOS is just plain fun and so well done, despite its budgetary limits. Have fun!
