Shockingly cheap and cheesy ending
When the movie ends I was shocked and then disappointed. A dream? The girlfriend just returns, and off course the wedding was cancelled last minute? He goes with her right in the spot when he said previously that he had to look after her troubled sisters? The happy ending renders all the premise senseless...
He could hang herself full of regret for having indirectly killed his sisters. Maybe a bit dark but at least, if all was a dream, a better ending IMO would have been that he lefts, alone, and full of sad for letting his sisters (especially the old one, Hester) and the old family house, but to find himself out there, to grow up.
