I really love Alex Garland, but this was a disappointment. This is not a series, it's a feature film with 6 filler episodes. Even when it's really well done like the pilot, soon you get to realize is just a gimmick to spend more of your time. So you be watching episode 3 and the protagonist will discover things the audience knew on the pilot, but we should be ok with this because of change in point of view. But in fact, you don't get anything new in episode 2 and 3. And what is new soon it's left behind because it never really mattered. And the science about it is somehow twisted for the convenience of the plot. In episode 6 I tough know we are talking about, but the big climax they promise is not delivered. For me, some of the best concepts of the show are in episode 6. At the end, Devs thinks itself as supersmart but believes so little in the audience they even explain the title during the climax. What a turn off. In some other multiverse I made better choices and didn't watched it.
