    Just a really bad movie

    Poorly written. Bad script. Weak acting. All adds up to a really bad movie.

    Another pointless lifetime movie!

    Another boring & predictable lifetime movie! Lindsay Hartley was ok init. There's much better Lifetime movies out there. One time watch for me. 2/10

    Oh No! Another Lifetime Movie!

    Normally I rarely watch Lifetime movies. I decided to try watching this having nothing else that sounded interesting on my TV. But I have to ask, why are Lifetime movies so lame?

    Why would a sister who hadn't seen her twin since they were children in an orphanage just decide that she's going to go after her and ruin her life? It wasn't believable to me at all. You'd think being a twin she would want to reunite with her sister but instead she sets about trying to destroy her. There's just no real motive for doing that I thought, as I was halfway through the movie at that point.

    Plus the actress, (Lindsay Hartley) who played her, was miscast as this character. Not that she wasn't a good enough actress she was, but she was too attractive. To see this beautiful woman with thick long lustrous hair looking like she just stepped out of a hair commercial, viciously killing people who get in her way, just seemed a bit of a stretch for me.

    The twins played by the same actress looked more like a supermodel or an actress which in reality she is the latter. The casting director should have chosen someone a little plainer, it would have been more believable.

    And this is what I mean about Lifetime movies. They don't put a lot of thought or effort into characters or plot. Maybe the problem is they just don't have a big enough budget. All in all, a total waste of 2 hours I will never get back.

    I would like to thank Davalon-Davalon

    Hello, I have never had so much laugh while reading a review,I absolutely agree with your comments, I loved them.

    I must also add that the acting is close to horrible,not speaking of the fact that I have rarely seen Linsay Hartley playing well. I often wonder why they employ mediocre actors while probably there are thousands of good actors without a job.

    What is more, I detest those comments that they are television films as an excuse for their being badly made They are films too, for goodness sake.
