Old friend from film school recommended this. (Don't worry he has since retired.) Wanted to like this but it was a waste of time.

One star given for the camera work and lighting.

Main character had little if any range. Plot was trendy multi-verse, parallel dimension, alternate universe/reality that has been done before with a fraction of the budget. So many long pauses. So many non sequiturs that even my young niece pointed them out, sci fi is one of her favourite genre of books and film. Dialogue was repeated and the conveyance of this took an eternity to happen. Rehashing of repeating of scenes with a little bit here and there is an artificial and inappropriate means of padding out the running time. Characters explaining the plot ad infinitum et ad nauseam was insulting (show don't tell better way to do it). We get it, Alex Garland you are intelligent, but why subject the audience to a repeated lecture on simulation theory. There was material for perhaps two or three episodes at a stretch but that would be too generous.

Funny when there is a flourish of high ratings at the start that pseudo intellectuals like to justify their mental superiority by following suit and pretending to be clever with the bot reviews.

Devs was a dull, dire, duff and drag of a series that had outstayed its welcome very early on.

If this is what passes for science fiction then there must have been a mass of lobotomized viewers and reviewers.

Save yourself some grief and read some proper sci fi by Philip K. Dick, Heinlen, Clarke, Asimov, Haldeman, to name but a few.
