If you look at the top most helpful reviews of this anime, you'll mostly see 2s, 3s or 4s. I honestly don't get the amount of hate for this anime. It doesn't claim to be something very unique or groundbreaking, nor does it attempt to be. So rating it low just because you wanted it to be something it is not, when it never claimed to to be that, is absurd.
It's a fantasy action adventure comedy with fanservice, and it does its job well in that department. Sure, it has a cliché good guy main character, and most characters are clichés as well, but that
doesn't necessarily make it a bad anime.
The story is decent and the pacing of the series is good. The animation is good and the music is okay. The sense of being in a fantasy MMORPG world is its main unique selling point for me. The journey of the main character and how he discovers himself while making allies and friends along the way is what I like about the anime.
If you're looking for a serious thought provoking anime, you're looking in the wrong place. It's a fun adventure of a guy who's in love and wants to become stronger to protect people/women set in a fantasy/MMORPG setting.
