    Geere gives a very lively performance and the rest of the cast is also strong. Not the happiest of topics, but Ill Behaviour, puts an interesting face on it.

    Ill Behaviour has some thoughtful things to say about right-to-life issues and alcoholism, and if you can buy into the kidnapping-to-save-his-life development, you might stick around for the series’ full six episodes.

    Its combination of black humor and gross-out jokes is a little bit on the hit-or-miss side.

    Ill Behaviour sadly dodges a lot of these difficult topics [How far should a friend go to help another friend? What’s the line between open-minded and suicidal?] in favor of easy love triangles, repetitious bickering, and extreme antics.

    Bain obviously wanted some wacky and dark collision to create the comedy, but there's just not enough of it to sustain much interest in a series that moves slow even when Showtime cuts it in half.
