Now, I haven't read this one recently, but hopefully you'll allow me the brazen chutzpah to share some thoughts and pics, right here. (I mean, it was already on my list, and I just figured-- let's get to it, matey)
Anyway, for me, Gemma Bovery was hugely significant to me around 2yrs ago, when it re-lit my fire to learn français, once and for all. Since then, by hook or by crook, I've genuinely worked much harder both via the DuoLingo app, as well as across my attempts to read French BD in general, getting me to about the mid-A2 level now in French, perhaps? (oof, it's a process, anyway)
Okay, what I find immediately, *highly* unique here is the way in which this BD combines both text and illustrative passages. I mean... sure, you can see this across many (or most?) children's books, but these days? It's more like... 'coucou, not how we do things in comics et BD!' XD
And of course, as English-speakers, we get these little bits of easy French words and phrases to discover across these comics. Not sure about you, matey, but it just really WORKS over here, I think, perhaps, maybe.
Without diving too absurdly deeply, there's a love-triangle working here, or quadrangle, or maybe just a bunch of unfortunates converging upon devastating topic of choice? :S
But the main thing, really? It's all about Joubert's (the baker) fascination with Gemma suffering across a bad marriage, her terrible taste in men, and just rotten, lousy work, at the end of days.
Now me-- I'm used to judging these works (heaven help my idiot opinion), upon a gathering of things, let's say, but this is one of those that, to me, examines some rather deep workings of a woman's soul, as seen from an immediate distance.
