I personally thought Fairy Tail was a good anime. It has good character development and they can be very relatable. The plot is great and it is not rushed. Fairy Tail can be a roller coaster of emotions. There are sad scenes and there are happy scenes.
It is overall a good anime but I would like to see some more development the relationship between the characters. It would also be nice if the characters had a goal from the very start of the anime and finish the anime with the character reaching their goal and it finishes.
Other then that it is a good anime and I recommend you to watch it.
