Zero no tsukaima F concludes the story in a great way and like I said it may not have the best plot or characters, but it is very enjoyable and fun to watch, the mix of comedy romance action and fan service is very good, if you don't like ecchi it might annoy you, but if you got over to the last season then it won't be a problem.
Story(9/10) - Great, has a good ammount of romance, it has a great ending and yu get to see character development.
Art (9/10) - pretty good, beautiful characters, good animation but not perfect, some details on animation make it a 9 instead of a 10.
Sound (8/10) - Great voice acting, the music is good but not great.
Character (9/10) - Even though they are cliche, they feel unique in some way or another, and each character gets some development even though it focuses on the two main characters, we get to see more about the princess and other characters, wich is pretty nice. Even tough louise may get boring at sometimes, she is still very enjoyable.
Overall (9/10) - One of the most enjoyable anime to watch ever, even tough it may be cliche at some times, it will be enjoyable and fun to watch till the very end, and the beautiful romance between the two main characters is a plus.
