This is my favorite anime by far, while I do love everything about this masterpiece, I realise that it's not perfect.
For the story, I find it strikingly amazing and fantastic, the problem is that there are plenty of plotholes and inconsistencies, but overall, it is really involving, it has everything, comedy, romance (witch I loved), high stakes and shows us the lives of the charachters in a dangerous world.
I have nothing to complain about the art of this anime, it is great, the charachters and enviroment look beautiful, it's really immersing and detailed.
The soundtrack of this anime is amazing and I have never seen anything
like it. I'm always listening to the intros and outros, and the melodies, played in battle and other moments.
MC is absolutely fantastic, all I have to say is that all charachters could have gotten a little more depth and developing, but it is not bad as it is.
Overall, I love this anime and I despise the fact that hating it has become so mainstream in the anime community. Hating on SAO is an easy way to get some people to agree with you and have they "let you in" in the community. Its retarded and whenever I see someone meme-hating on SAO I prepare myself to discard they opinions to the trash bin they deserve to be. THERE IS NO PROBLEM on disliking it and pointing out it's flaws, but it's been six years now and it has become overdone, I can tell genuine criticism from the meme-hating.
Give it a try and don't listen to the haters and you are likely to love it as much as I did.
