I don't really have any previous knowledge of most of the actors or seen or heard anything prior to watching the movie apart from the trailer.
I won't go into plot details as there are other reviews that did that way better.
What I do want to say though is: set your expectations right!!! If you liked what you saw in the trailer, hey...if you liked the poster and know what "homage" means as a genre then go see it! But if you are not aware of those things....please don't come back here giving ratings of 1 and saying how bad this movie was.
It's one of those artsy movies that you'd better watch on your own in my opinion. The universe is very captivating. The characters are likable and relatable. They are pure and innocent in a way. There is no nudity in the movie. And the gore is 80's style, but you could probably go with a tween or a teen. It's way safer than what Hollywood offers to that audience.
I really enjoyed the movie. If you have open mind, some time and know what to expect it's a nice treat at the beginning of the autumn. If some of those things do not apply to you, then you'd probably skip or leave the cinema.
