Do you mean that you don’t agree with the criticism, or that you don’t understand why someone would dislike the story? I feel like the former is the more understandable sentiment, since the latter is just a matter of personal taste.

After a quick read of critic and user reviews through metacritic, the complaints seem pretty consistent regardless of how I personally feel about them. A ton of them say the plot was barebones and predictable. Even the glowing reviews from critics seem to mention that the plot only gets the job done.
