Mother, May I, or paraphrasing, Mother, Should I give this a go?
I think so yes, first of all, for our new male lead horror actor, Kyle Gallner, emphasis on male. A lot of new scream queens lately, which of course is a good thing, seeing people embracing this genre and becoming a symbol of it. But we do lack on the male part, we still rely heavily on Tony Todd, Lance Henrikssen, Robert Englund and so on.
But honestly if you remove Mr. Kyle from the equation, I have to say, Mother, May I is overall a little bland. I won't call it generic, it just doesn't offer as much as it promises, yet it does manage to hit some soft spots, just without a real echo to them.
So for a die hard horror fan, yes, for a one time view, this movie should be on your list, with the clarification that it is a psychological war here, with a little bit of mystery, but no horror, or tension or scares.
If this is what you're looking for, you might actually be pleasantly surprised, I hope. A movie in the type of Goodnight Mommy, The Lodge, or It Comes At Night.
Definitely no The Ritual sadly.
So all in all, another piece of the horror puzzle has been found, take it or leave it.
Cheers!
