I watched Mirror Mirror many years ago back in I think 1991. I seem to remember it being a pretty good film. After all these years, with the help of EBay, I found another copy and just got done watching it. Very interesting film.
The movie starts out back in the 30's. A young woman appears to have murdered her friend with an ominous looking mirror in the background. Now, skip to present day (1990), Megan and her mother have just moved into the same house in which that murder took place. The same ominous mirror is still in the house and instead of disposing of it, Megan has grown a liking to it. Now, Megan is a teenager and dresses like a goth kid so naturally she is tormented in the new school she is going to. But, she discovers that this mirror is giving her powers and her tolerance for the kids at school is wearing thin.
I know this description of the movie sounds a bit cheesy but you have to watch the movie to really catch the atmosphere. The camera angling is absolutely wonderful, the score is wonderful, the acting is okay (except Karen Black who is always welcome), the special effects are okay considering that this movies strong point was its atmosphere. And the ending is quite original. All in all, I give this a 7/10. Good effort.
