🔍 Search on JustWatch →This is a comedy that knows its limits. Doesn't reach for grotesque when irony is enough, doesn't ask the audience to take things too seriously.
Worth watching for a good mood and a couple of genuinely funny moments. Doesn't promise depth — but doesn't pretend to have it either.
Good for watching with people who need to unwind after a long day. Not for those seeking depth.
