Watched this in freezing cold Ghent, so enjoyment may have been influenced by the fact that it was experienced in a warm dry place. Subtitles in French and Flemish did not contribute significantly to the pleasure, but didn't detract that much either.
Just your basic romcom, with a mental illness overlay. Nice performances, especially by Robert De Niro as the OCD dad. Sentimental and manipulative but it worked for me - lump in throat and tear in corner of the eye by the end.
