Most love triangles want you to pick a side. The Sun Never Sets makes that surprisingly difficult.

Dakota Fanning plays Wendy, caught between her older boyfriend Jack (Jake Johnson) and a younger ex, Chuck (Cory Michael Smith), who comes back into her life. At first, Chuck feels like the obvious choice, especially since he offers the possibility of the family and children Wendy wants.

But the movie keeps complicating things. The more you learn about both men, the harder it is to know who you’re rooting for—or what Wendy is going to do.

That uncertainty is what made this work for me. It’s unpredictable without relying on some huge twist, and my loyalties kept shifting right along with Wendy’s. A well-done, enjoyable love triangle that never makes the answer too easy.
