We've got four entries on the comics list from Asterix. While there are four different books on the list, there are quite a few similarities. Besides, I've read a lot more entries in the series, so it makes sense to treat it as a whole.
There are a couple of layers to the books. The first times I read it, I just saw the basic jokes and had a comic book set in the past. As I grew up I started to understand some of the history jokes and the juxtaposition of the two worked. Now, the broad jokes may not land as well, but understanding the mafia subtext in Asterix in Corsica becomes a lot more amusing. The books deal in pretty broad stereotypes, but it only becomes amusing when you get deeper in it. Obviously, the books play fast and loose with history, but at the same time there are enough reference sin there that it feels like it tries - using the history without it getting in the way.
At the same time, there are times where the plotting isn't as tight. It can take a while to get going and the action is pretty constrained through parts of it - the diversions for jokes don't always seem worth it, while they leave the final resolution to the last two pages, which feels like a letdown. It's unsubstantial, which I felt some books did better than the other, but which I also remember being good elsewhere. This may not have been helped by the four stories being journeys away from the main village, where that village works as a better base. It means that at this point, the books were fine, but at my age, and having read more, not amazing.
