You mean the oversized Cylon Raider? 'Pancake with an engine strip' is a low bar to clear when it comes to ship design.have you looked at the shape of the millenium falcon and valerians ship?
Six. Three of them from France.How many ' character embedded in a block' stories can you recall offhand?
Seriously, I've read all three of the Valerian stories used as examples in that article and non of them are appreciably "Star Warsian". I'd take the idea more seriously if you'd told me Valerian was one of the inspirations for Doctor Who, what with a human girl from the past swooped off as companion to a time-travelling spaceman.
Seriously, this whole things comes off as a showcase of how easily it is to pick out things that remind you of Star Wars while reading Valerian rather than the other way around.
