Very fine actors we have here, to a story that you have to ... well get into. The premise is "easy" or at least seems that way. Especially considering how fast everything seems to move at first. But when you skip steps - well in the end the step you skipped may come back to haunt you.
Or in this case the main characters. Love can not be conjured up - it can be built over years sometimes, And it may be something that is going to happen here too. But it wouldn't be a good movie, if everything went smoothly and without any obstacles ... still the movie is almost 3 hours long and the pace slows down quite significantly.
So I do understand if some people have issues because of the length (no pun intended) ... yes (minute) size does matter. Keeping things fresh too - it does try that out and we have quite a few situations. Some that we may have to figure out ourselves. Can you dig it?
