I don't understand all these bad reviews. It must have something to do with not liking the French language, or not understanding the humor. If you've watched it dubbed in English, it is probably not good either.
I thought it was a great show. Low budge, with short episodes of aprox 24 minutes. So, easy to sit trough. I was so pleasantly surprised. I watched the entire show in one night! It is fun. It is light. It is truely a feel good scifi show. It's not an outstanding show, hence the 7, but the humor and the feels were great!
French humor is always a bit weird. French movies are always a bit weird (mostly). Thats what so great about them. If you understand that, you'll like the show.
