[4] The cast also includes Monia Chokri as Bastien's mother Violette, as well as Jeff Roop, Pierre-Luc Lafontaine, and Thomas Laperrière in supporting roles.

The website's critics consensus reads, "Moody, sensitive, and subtly layered, Falcon Lake captures the intoxicating horror of young love.

"[8] However, online magazine Slant commented that "the inadvertent effect of the brooding, almost overbearing gloom that shrouds Falcon Lake is that it manages to sap the life out of its initially carefree depiction of young people’s emotional lives".

[9] Metacritic, which uses a weighted average, assigned the film a score of 71 out of 100, based on eight critics, indicating "generally favorable reviews".
