The title character in MAMA is a restless spirit who moves in creepy, unnatural ways. Or, if you are Javier Botet, the 7-foot-tall contortionist who plays Mama
, ways that are natural to you:
It's crazy how the movies find homes for tiny people, giant people, people who can make their elbows go backwards... and people who'd rather spend their days in a fantasy of their own making. Like, y'know, us.
And, this is a reminder, there is no limit to what CGI can do when it is crafted with artistry, but the real thing is somehow always a little more powerful. "The audience doesn't know, but it knows."
