Bill Milner, playing an offbeat nerdy looking hero, commands every scene he appears in, which is pretty amazing, since Maisie Williams steals every scene she's in with her own unique beauty and a to-die-for personality. Ya, I've been a fan of hers since day one on "Game of Thrones."
"iBoy" has plenty of action, but it doesn't skimp on taking the time to get inside the character's heads. The special effects look cool, without overpowering the camera work, and the sets are perfect for the story.
Rory Kinnear, who I shall always remember as the Creature in "Penny Dreadful," gives us a near perfect villain, although I really wish they had given him more screen time.
Take a leap of faith and accept that having parts of an iPhone embedded in your brain turns you into a talented cyborg, and you will have a grand time. In other words, don't pick the movie apart. Just enjoy it.
