Magmell opinions?

Hey guys, I've only started watching anime, and the first series I completed was Ultramarine Magmell, and I personally thought it was pretty good, however I've realised it's a pretty disliked anime. Now, considering that I liked that, I have high hopes that I'm going to like a lot more anime throughout the year.  But my question for you, if you have watched Magmell, is

Did you like Magmell or not? And Why?
