Post an anime you like and I will tell you why it's shit.
>Protag is male
>2 male characters in the main cast
>Shit ton of females in the main cast
>All the females like the protag
What do you call this genre then?
>It tries to have a plot and focus on that plot, but the plot is shit
For GGO I'll give you that, but for SAO itself, the plot isn't bad, it's just generic game shit with harem hijinks. That doesn't make it bad, just average.
If anything the only problem with the whole franchise is how serious it tries to be.
>Just because it has a lot of female characters doesn't make it a harem
