10/10 Masterpiece. Plot progression is certainly there albeit there is a lot of world-building in first few episodes which is somehow conceived as lack of plot progression. But I would like to remind everyone again that whole concept of Konosuba series is comedy and fun adventures. If you are watching these series for sake of plot progression, you are certainly in wrong place. Do not force yourself to watch this because it is popular, no way you are going to be able to enjoy what this series offers with such mindset. Realize what this anime will offer you, relax your expectations and embrace the random fun high quality comedic presentation.

Animation: 10/10, Konosuba series always had high quality production, amazing effects, no random blurs. It gives you what you would expect of a high budget anime. Albeit not as high budget as SOA or AoT.
Comedy: 10/10 Not one episode that I wasn't bursting out laughing.
Characters: Show is filled with unique and very likeable characters.
Plot: Whole plot is oriented around Megumin and YunYun and does great job at establishing background for these characters. And plot is filled with random fun events.

For sake of being objective I really wanted to list cons as well, but honestly, there are no cons. And only cons I have seen listed are coming from people not realizing the category of this anime and expecting from it something it never promised in the first place. Konosuba won't give you brutal dark stories or multi-season deep extremely detailed convoluted stories - but expecting such things from Konosuba goes against what konosuba is and setting right expectations is crucial for a human's enjoyment of any entertainment medium. As I said, don't force yourself to watch this because it is popular, only watch this if you are interested in fun, adventurous comedy anime on isekai setting.
