Will Ferrell and Rachel McAdams in Eurovision Song Contest: The Story of Fire Saga.

Will Ferrell used to be a sure-fire comedy guarantee: There was a stretch when it seemed he could do no wrong.

Alas, that stretch is long behind him now, and Eurovision Song Contest: The Story of Fire Saga continues his recent streak of lousy-to-mediocre films. This one falls somewhere in the realm of mediocre.

On the eve of the infamous Eurovision contestโ€”the song competition that birthed the career of ABBA in real lifeโ€”Lars (Ferrell) and Sigrit (Rachel McAdams), lifelong friends and members of the rock-duo Fire Saga, are taking one last bid at fame. However, they are terrible, and are hated by most of the people in their Icelandic hometown, including Larsโ€™ father (Pierce Brosnan). A tragic boating accident thrusts them into the competition in which they represent their countryโ€”and many unfunny musical sequences ensue.

Ferrellโ€™s wigged schtick grows tired early onโ€”and since the film is two-plus hours long, we are talking a lot of unwanted shtick. McAdams, who can lip-sync with the best of them, is actually quite good here, and nearly saves the film with a warm, funny, earnest performance. Her characterโ€™s obsession with magical elves is a potential funny subplot that isnโ€™t adequately explored. Directed by David Dobkin (Wedding Crashers), this movie wouldโ€™ve benefited from a shorter running time.

Itโ€™s hard watching Ferrell founder in stuff like this; his career is in need of some major adjustments. Heโ€™s too funny to be goofing around with subpar material.

Eurovision Song Contest: The Story of Fire Saga is now streaming on Netflix.
