All of the actors are very good and the storyline is amazing.

Crossing the Line has a good distribution of screen time. The main couple gets almost all of the time but the side couple gets just enough to gauge the story of their relationship without taking away from the more dramatic nature of the main.

It is very good and have a nice balance of drama and painful scenes. There is enough sweetness to stop the emotional and dramatic scenes from sending the whole stories into chaotic messes but there is also not too much sweetness which could have made it quite boring.

Also, all of the couples face adversity in one way or another which helps to make them seem more real and draw the viewers in more.

Definitely worth a watch and just to let everyone know, there is a sequel to Crossing the Line which is already out.
