No pun intended - even though the pun was one I could not miss out on. It's almost like the movie went fishing for it ... ok another one. Don't expect the movie to be a comedy though. We have full on drama here. Situation(s) that will test our main character ... and her love for someone - more than one (another pun).
It is overall a decent effort and look into the human soul and psyche. When you are about to marry someone - you should be sure, that is the person you want to spend the rest of your life with (and/or their life that is). Of course they should be sure also.
Getting on ... a trip is not a bad idea. What you might do on that trip on the other hand ... well it can have repurcussions. Even if nothing actually happens? For you (or her/them) to find out.
