dude, just to be clear, the first arc is pretty much a 17 year old's .hack fanfic that he wrote on his site
and the 2nd arc is also bad

the 3rd arc is a lot better as it's a fantasy shooter
anyways, his other short stories from his old site weren't too bad

and accel world was actually interesting if you're not a moron and actually try to find the reasons as they're actually there in AW, unlike SAO, but a lot of people hate AW because they're too stupid to look for reasons or hate a fat mc
