CSM was actually reviewing the edited-for-home-media, G-rated version of The Parent Trap. If they were to review the uncut version, it would be rated 15+, or 12+ at the least, because there is a lot of sexual content (romantic kissing, partial nudity) and inappropriate language ("oh my God," and three possible implied uses of "the f word"). Remember, this movie came out when the MPAA rating system was a little less strict. This would easily get an R rating if released today! Red light for ages 10 and under, yellow for 11 to 14, and green for 15 and over.
