Sure, everything flowed well and it is easy to enter that world and understand a lot. Eventhough it might not be for me, since it's a little strong and melancholy, I have to admit the overall quality is very high.
I'm not found of Frieren's design and Fern dead eyes.
I do not like the recuring anime trope: old people are very short even if they were average to tall in height when young. I had to convince myself for all the ep that the old dude was Himmel.
But aside from these 3 minor details, I like what I've seen.

Somehow, Qal was probably the character I liked best, design wise. His appearance was too short, but I like that he was a genius mage for his generation. Many shows would need a vilain that good, funny he was just a 5 minute clip in a show that doesn't need him hahaha.
