A única parte boa desse drama é o jogo de realidade virtual (genial) do Seju - porque todo resto é um lixo. Song Jae continua não sabendo criar protagonistas femininas.
I agree with @bayanoh - there were a lot of massive plot holes. Nevertheless, the overall experience was simply amazing. Special effects were top-notch, the plot was very fresh, acting really good (even in case of PSH whom I have a long-lasting love-hate relationship).
...the plot holes were too, sadly.
