The first Asterix adaptation not to be taken directly from one of the books but instead is a combination of Asterix the Legionary and Asterix the Gladiator. The cut-and-shut story is a bit disjointed as a result, which might test your patience, especially if you don't like seeing the books jumbled.
Life continues as normal in the Gaulish village as Panacea, the niece of Chief Vitalstatistix, returns fro her studies in Rennes (then called Condatum) and Obelix falls head-over-heels in love with her. Too bad she already has a boyfriend in the shape of Tragicomix, a handsome stud. The surrounding Roman outposts warn Decorian, a new recruit, to not anger the Gauls out of fear of a yet another pounding. Decorian does not heed this warning and manages to capture Panacea and Tragicomix. But before Asterix and Obelix can rescue them they have already been re-captured by slave traders and sold off to be butchered in the Colosseum.
Asterix and Obelix then go undercover in order to get them back, pounding many Romans along the way. The animation is wonderful and the humor is enough to keep you chuckling through-out, but I can't help but think that the books it was adapted from would have made better individual movies. Caesar's presence feels arbitrary and it lacks a decent villain.
Still a fun time.
