What was good could've so easily been grand, and that's what failed this film, and that's a real shame.
I'm no filmmaker, but if someone gave me this screenplay, I would've rid it of some major plot and technical issues, and had at least 30 minutes cutting here and there, particularly the many unnecessary, long, and repetitive scenes. Although the pacing was decent, those terrible scenes made this film feel dragged out and felt like it was more than 3 hours long. There was just way too much filler, for the little substance that was stretched out to its 127 mins runtime. Cutting/editing it down to 90 minutes would've been perfect for this film, and done it so much justice.
The visuals and SFX were outstanding, and the ship and its inside on par in creativeness and originality with Hollywood blockbusters. The cinematography was great, and the sound/score on point. The concept of the story was different in a clever and unique way, and that's refreshing.
I liked this film, but I really wanted to love it. Nevertheless, it's a well deserved 8/10 for this epic Ruskie sci-fi flick.
