Wing Commander is space without the opera. It's humanistic and free of woo. There are no supernaturally gifted gurus wielding magic. The good guys do not seem predestined to win. Everyone in this big cosmic drama is just an ordinary person (or other sentient being) muddling through familiar problems.
Seems like this reviewer wanted the movie parts to be more wacky and fun. Given that the premise is essentially (spoilers) space Nazis attempting a coup, I'm not sure how this would have made sense. If you want wacky fun, there are plenty of other space movies that will oblige you.
