Just stop the madness.
This film is fine for a travel infomercial on HK. But please stop comparing this to the "Before Sunrise" trilogy.
It's not even close. The acting is terrible. The script has the depth of a grade 10 English class. You're basically comparing a piece of Monet art to a high school art class imitation. Yes it pays tribute to the art but this is mountains away from the original.
Again fine as an airplane movie, I didn't say I didn't enjoy it for what it was. But it's as shallow of a movie if you can call it that as it comes. So just stop. It's insulting to the original art.
