“Mean Girls” (*** out of four) was a colorful musical adaptation of the 2004 classic about a new girl in school (Erika Henningson) trying to find herself and gets taken in by a nasty clique called The Plastics (Taylor Louderman, Krystina Alabado, Kate Rockwell) who make their own rules. Not as “fetch” or as ruthlessly clever as the original film but agreeably performed and designed and entertaining. One complaint: why did they cast actors for Regina George and Karen Smith who look exactly alike? (Sometimes it was hard to tell them apart)
