too many questions (like: what's it for, whats the point?)

i have recently watched mike cahills new film "I Origins", which, as his previous film "Another Earth", has a very tight narrative and an open end. i don't mind movies that do not answer everything, but:

this movie has just only open questions, and no answers at all.

with i origins or another earth, it works well, because each film has only one question the whole story is about.

in "The Signal" there are just too many.

is it a sci-fi film? is it a thriller? is it a found footage? is it a philosophical question? what is this film? i feel like it tries to be to much at once, and fails to be anything at all.

from the first 30 minutes i expected it to be a kind of sci-fi thriller, which it wasn't.

towards the end it tried to be philosophical, in the end i did not know anymore what kind of movie it is, and i do not see what STORY it wanted to tell me.

it almost seems as if this movie was supposed to be the first of two parts, its just in every way unfinished.

after the abduction, when nic woke up first in the underground facility, i constantly was thinking: whats the point? what for? what are they trying to do?

the "aliens" in dark city had a very specific goal. what was the goal in The Signal? was there even one?

some fine visuals, okay acting by brenton (EVERYone else pretty failed in acting, even lin shaye, whom i usually adore), but a highly convoluted script that really goes nowhere, does not tell a story and leaves me asking: what's it for? whats the point?
