I watched the movie Twitches. It stars Tia Mowrey (Sister, Sister) and Tamara Mowry (Sister,Sister).
Two teen witches who were separated at birth and were adopted by two different families meet on their 21st birthday and must use their powers to save the world in which they were born, where their birth mother still lives.
I give it 2/5 stars.
I liked this movie, but think I have seen it one too many times (thus the low rating)
