Here's a quick TL;DR rundown of Haiyore! Nyaruko-san
1- You've probably seen it before. There's nothing special about this Anime. The story is just a sequence of events thrown together so as to fit as many gags as possible in, the characters are recycled, the gags are overused. If you're looking for plot, or great comedy, you won't find it in Nyaruko.
2- The Anime is character based. As with all Anime targeted towards an Otaku audience aiming to be as marketable as possible, Nyaruko's strength is with it's characters. They're memorable, they're funny and they each have their own distinct trope. Some people maybe see this as a bad thing, and in a sense it is, but for what Nyaruko is aiming for, it's succeeded in making the characters as fun as possible.
3- Because it's a character-driven anime, the art and character designs are great. Who cares about plot when you have these beautiful pictures to look at? Or so they want us to think. It's not that bad though. They designs are clear-cut, distinct and present the constant moe and service very well.
4- The music is good. Catchy OP; better ED. All's nice and well. Of course, they're just OPs you've heard a million and ten times before in other Anime, and Nyaruko doesn't even try to be original. It knows it doesn't need to be.
5- It's a light hearted watch. As I've said on countless other Anime, don't take it too seriously. No; it's not GREAT, it's not groundbreaking and it certainly won't appeal to everyone. But if you want something light-hearted and fun, and you enjoy squealing at moe characters and laughing at over the top gags, then you'll probably enjoy this.
