I really recommend not wasting your time/money on this movie. It's a dreadful, zero-star movie! I don't think that what follows contains any spoilers, because a story has to be cleverly written, and to have some narrative plan to conceal (and to reveal only in the telling) in order for spoilers to apply. And this movie doesn't have that. But either way if you're worried about spoilers, and you really want to watch this movie, then you might want to stop reading now. But afterwards, come back and see if I didn't tell you so.
I went into this movie with a completely open mind, knowing only that it was something about a murder suspect with godlike powers. That sounded like my kind of thing.
When the title of the movie ("Mortal") came up unobtrusively onto the screen, in reasonably stylish serif all lower-case text, I thought oh, that's some nice design. Then, below it, faded into view a dictionary definition, and I frowned and shook my head. Dictionary definitions are always a sign of a lack of taste and imagination. In this case they'd even completely missed the point of what the word mortal means.
Then came a long multi-minute montage of landscape shots. Too many of them, and all held too long. Now there's someone wandering about, sometimes limping, sometimes not, camping, dreaming about fire, oh the trees do seem to be kind of burned.
Ten minutes in, a very unpleasant juvenile delinquent gets a surprise. After that there's an interminably boring (15 mins) interrogation, where some uninteresting (annoying/confusing) phenomena take place, but mostly I was thinking "you/he/they/she wouldn't do that".
At around the 30 minute mark there's an unbelievably stupid scene in a helicopter with a bunch of alleged professionals behaving incredibly and frustratingly (and infeasibly) stupidly and unprofessionally. For example, at 29.30, we the audience can see the antagonist (yes, he's an antagonist, not a protagonist) starting to wake up. A full minute and a half later we can still see the medic fumbling and unwrapping a second dose of sedative (sedagive: now there's a movie!). Another 20 seconds of inaction later and they're all electrocuted unconscious and they've had their chance. Just so disappointingly badly written.
The rest of the movie is a dull trawl through some kid's petulant and unjust temper tantrums, and everyone else's unaccountable incompetence and stupidity. Yeah, turns out he's a descendent of Thor. The god. Whatever. This is just a terribly written snore-fest best avoided.
Shockingly dreadful. Yes, that was meant to be a pun that you'll hopefully never get because you'll do something better with your time than watch this garbage.
