I kept seeing previews for this movie when I was at the theater and it 
looked stupid yet scary, so I decided to take a chance on it.
The movie isn't low budget, it's a quality film.  The ghost character 
could use a little more work in it's design and quality of the 
graphics.   The movie starts out with the Dad bringing his 2 little 
girls into a car, not knowing what is going on, except for a few seconds
 of radio station playing in the movie.
The Dad takes the 2 daughters, the baby not even in a car seat, and 
drives hurriedly and carelessly through the snow and ice roads.  They do
 run off the road and all seem to have survived the crash, get up and 
wander around the woods until they come to an abandoned home where they 
take refuge.  The little girl is looking out the window and says "I see a
 lady out there" foreshadowing the MAMA ghost.  The Dad then takes a gun
 and points it at the little girl's head looking out the window.  
Suddenly that Dad is gone and the 2 girls are alone.  You never see MaMa
 at this point, but know she is there.
My criticism about the above is, why would he take the girls out of the 
car and into a shelter when he could've just killed them all right 
there.  He seemed to have been taking his time to kill the children, 
when apparently he killed his wife right away.  Try to understand the 
movie?  No.  All it seems to me is the opposite of "The Ring" in a way 
that the main scary ghost character misses and wants her baby as much as
 Samara loves her Mommy.  The girls then decide that MaMa is a bad 
person and evil as soon as they are in the real world after being 
discovered 5 years after they were lost.
And who waits 5 years?  Why weren't the cops out there if they found the
 car that was wrecked in the first place?  So many things wrong with 
that, but everything leads up to the story and why the kids were alone, 
they only had MAMA and now they are free of her and want her gone.  
Somehow they have MaMa's ashes from the 1800's and finally "put her at 
rest".  The ending wasn't great.  Very low budget quality effects on 
that one, but another story down and watched. 
Worth the time?  I don't think so, unless you have nothing else to do.  I luckily did not pay money to see this at the theaters.
I score this movie a 5 out of 10
