I love it! Korean music production is just not the same. No matter how much C-pop I listen to, C-pop production quality just can't match K-pop...
The opening theme is completely different! I actually think this color scheme is better than the pink one in the Korean MV.
I love Taeyeon's hair, especially in the greenish-gray military outfit. She actually looks like a leader with 8 girls under her instead of the kid leader. Yoona looks gorgeous in her first shot. >.>
