In my personal opinion, Toradora was a really good show. I enjoyed the full ride, espacially the good developed characters over the course of the series. Some parts were a bit slow in my opinion, because for example the first few episodes took pretty long introducing the characters, which is okay considering this isn't just a 12 eps season, but a whole 25 eps closed story, which is pretty neat if taken to comparison to open ended Anime like Nisekoi or Boku wa Tomodachi ga Sukanai. I really loved the main characters and the secondary characters were pretty okay, too, while the minor characters come of a bit... See full review
I really don't know, what everybody's problem is. If you're not into those anime, why do you watch it?
I honestly think it has a great sense of humor, the music pretty good and the characters are good as well.
I had a great time watching it and anyone who enjoys stuff like OreImo, Haganai or similar anime, will enjoy this one as well.
