A John Apart’s review published on Letterboxd:
I'm not much of a gamer anymore, but when I do play I tend to play the games I loved when I was a kid ... so the retro feel to so much of this fun, warm-hearted paean to the history of videogames gave me much joy. It's essentially an electronic version of the 'toys waking up when kids aren't around' idea from Toy Story, but hey, the classics never go out of style, right? Ralph is the villain in his game, and he's sick of being sidelined, so he journeys through every game in an arcade trying to better himself. It's got some big laughs, a neatly constructed story, and a hugely entertaining villain. Without checking back over what I've seen, I'd say this is probably my favourite animated film of the year.
