Some of Mr. Williams’s performances were criticized for a mawkish sentimentality, like “Patch Adams,” a 1998 film that once again cast him as a good-hearted doctor, and “Bicentennial Man,” a 1999 science-fiction feature in which he played an android.

I found [Christoph] Buchel’s appropriation of the boat in which so many migrants lost their lives a vile and mawkish spectacle in the context of the biennale.

Feeling sick, queasy.

Sickening or insipid in taste or smell.
