Filmsquish reviews it here, saying:
Murnau's Sunrise makes inspirational waves, both in the way his dramatic plot takes us to extremes of emotion while still using well known devices such as irony to tell his hero's story. All to say it's no surprise that this film's made the list of the Top 250 on IMdb. This is classic storytelling, and though old, genuinely original.
