Spiderhead banks heavily on its lead performers, and both Hemsworth and Teller deliver the goods when the plot struggles to. Very early on, you smell a lighter version of Ex-Machina (replace the robot with mind-control drugs), with several random tonal shifts. The writers (Rhett Rheese & Paul Wernick) are known for tickling the funny bone, but I think this film would have benefited from a more serious, psychological approach - which, credit where it's due - it did to some extent. The romantic subplot, while nice to see, ended up being exploited (such a cliché) as expected. The conclusion isn't all that exciting, because by then, Spiderhead has fully embraced its weirdness and is unfortunately stuck between making viewers care and giving closure to the plot.
