Well, it only took 7 years, but this movie has finally been commercially released in the US. (If you have any interest in seeing this, you may want to do so quickly. Some Asterix movies last on streaming for a while, but some disappear quickly.) In Asterix: The Secret of the Magic Potion (original title: Asterix: La Secret de la Potion Magique), based on the long-running French comics series, Getafix, the druid who makes the magic potion Asterix and the other Gauls in his village (the French version of Vikings) use to make themselves stronger and protect themselves from the Roman Empire, realizes he isn't getting any younger and decides to go in search of a successor.
This is a worthy follow-up to the previous computer animated movie Mansion of the Gods. The script flows nicely and everything works well together. The story is slightly more complex than you think it might be and makes you invested in what will transpire. Comedy is good, able to please kids and adults and to bridge the gap to non-French audiences (more so than that recent live-action movie on Netflix if you've seen it.)
Secret Potion makes good use of distinct characters both old and new. Though Getafix is a main fixture of the comics, he often isn't center stage. His movie is a bit of a showcase on his wise and amiable values and nature. The movie introduces Pectin, a young schoolgirl in the village and budding inventor who looks up to Getafix. She's an earnest character and she and Getafix make a good team.
If there are any complaints, I feel that Asterix is a little too quick to anger. Yeah, it's not like he's never gotten annoyed before, but he's one of the more level-headed characters, and it feels like he is losing his temper due to plot reasons.
One of the best parts is the new villain Demonix, a banished Druid and Getafix's former friend. With the exception of Julius Caesar, most of the Asterix villains are one-dimensional cartoon characters. You get a few cleverer ones, but even their personas are kept simple. Demonix has a little more personality too him and steals all his scenes. His desire to obtain the magic Potion is a selfish one, but there are moments where you say, "He does have a point." He's also a clever one. It takes a while to figure out his plan but when you do it all makes sense.
Animation is colorful and manages to keep the essence of the original 2D-illustrations intact. Unfortunately, they keep the original "larger lips" for the black crew member of the pirate crew Asterix and pals keep running into. They really should know better by now.
Highly recommended. This is honestly one of the best Asterix movies and even if you're unfamiliar with the character, it's easy to jump into the story.
