The I still love U PV is amazing. I really like how clean and simplistic the whole thing is, like it's a long long APPLE ad! Especially when the words show up after the clapper. Love it! I like how it's zoom in zoom out too! (Kinda like Mika's LIFE PV with the focus on her eyes.)
I think the laughing was intentional, because it seemed like they were acting it, too unnatural to be real. I don't know what was the intent, it was weirdsy, but nonetheless, still cool.
They all look fabulous.
