It's been done to death, it's full of cliches, and the harem aspect is annoying as always. But, you know what, I found the show pretty enjoyable; for the most part.
Although, if I'm being honest, I think most of my enjoyment is because of Emilia. I liked her character a lot, and without her I'm certain the show would have been a complete wreck.
The ending was beyond stupid though.
