I'm loving Joseph! I never watched his previous works, and when the news about his casting came out I was indifferent, thinking that this will be another idol adaptation. He wasn't that impressive at his starting scene and too boyish-pretty for my taste. I still think he's a bit too modern faced, BUT! His acting definitely gains my respect. He has expressive eyes, and despite his modern look he got his mannerism right for a wuxia period drama.
BTW, HSDS is close to 3 billion views, if you add up the numbers for each week

I'm quite optimistic now that it will round up to 5 billions at the end of its run. Douban score constantly increases too. I wish it will eventually reach 7, but I will be grateful if it at least passes 6 (yea, no thanks to those dang slo-mos. Nowadays people just throw Douban scores just based on the first episode!).
