Boys before flowers.
1. The guys were super super gorgeous. Each one of them
2. Everything was done in such a grand, beautiful way. I actually felt the power of F4 without seeing them as heartless monsters
3. I felt all the character matured from day 1 till the end. Not because the story said they are maturing but they literally looked the part.
last but not least Goo jun pyo! awesome. He reminded me of the original character looks and everything combined.
