If you enjoyed this movie, you might be more forgiving or less concerned with its flaws. There are numerous issues with the film, both in terms of the narrative and basic logic. The excessive use of slow motion, rampant lens flares, weak scripts, and incomplete backstories are major drawbacks. Moreover, it's hard to overlook the absurdity of an interstellar spaceship, supposedly capable of star travel, being powered by a mere coal furnace—a concept far removed from our current technological advancements.
