After becoming more and more fantastical in the past couple of seasons, it looks like season five of Arrow will have a back to basics vibe. This new extended trailer suggests a darker, tougher tone, as Oliver assembles his new team and gets them trained while a new bunch of villains look like they’re getting their act together as well. Plus we get our first footage of Dolph Lundgren in action (albeit very briefly) in this season’s flashbacks. Plus, Prometheus looks downright freaky. Overall, this is looking very promising.
