The only thing I enjoyed was the soundtrack.
I'm not good at writing reviews, so bear with me.
If you're ok with a complete obvious story with plot holes and deus ex machina, then this might be enjoyable for you. If not, then skip it. Its a typical SAO-plot with some psychos doing psycho stuff to get someone killed in real life. While a few scenes are enjoyable, the rest is completly obvious and you know quite some time ahead of whats gonna happen because the storyline is so straight and simple.
