I loved it; others hate it.
From what I can tell, this seems to be a very Love It or Hate It type of film. Throughout the movie, many tropes and cliches are played for all their worth, but their use never bothered me because of the honesty with which they were used. Furthermore, the honest and heartwarming acting of the characters sold the movie for me. Others find it unfunny and despise it. However, you'll probably be able to tell if you're going to like it early on in the movie. If you're looking for a big-hearted romantic comedy, then go ahead, and there's a good chance you'll love it like I did. Otherwise, you might want to give it a miss. But then again, I'm a hopelessly romantic and emotionally starved Hikikomori, so perhaps that has something to do with it. Personally, I give it a 10/10!
