Interesting idea, poor execution

Rating: 4/10 (2 March 2018)

The premise of this movie had a lot of potential, but it didn't meet my expectations.
The characters were either completely forgettable or annoying. Some of them died because of their stupid decisions as if the characters only existed to embody negative character traits. For example, two characters started fighting each other while being surrounded by aliens. Another character went crazy from fear and messed up the lights that were keeping the characters safe. I didn't feel scared at all, because I didn't care about what happened to the characters.
In fact, I kept hoping someone would kill Riddick, because he was so unlikable. I feel like I'm missing an inside joke, because there are so many reviews praising him. He crashed the ship, killing most of the people on board. His lines were cheesy and edgy, his glasses looked silly, and his night-vision made him an obvious plot device. Even at the end he was still playing mind games with the female lead (whose name I forgot) and wanted to abandon the other survivors, showing that he hadn't got redeemed at all. The worst part is that his casual attitude made me feel like he was never in any danger. He was a male Mary Sue who had the plot revolving around him. Characters in horror movies shouldn't seem invulnerable.
Also the planet didn't make any sense. Why would the dominant species on a planet that experiences constant day be scared of daylight? The planet didn't get enough eclipses to let the aliens come to the surface to hunt regularly. If they hunted all other species to extinction, what were they eating between the crash-landings? Each other? Then their population should be shrinking and not be so massive. The problem could have been fixed by giving the planet extremely long days followed by extremely long nights, like some real planets have.
