Most critics come away warm towards Wonder, and the praise gathers almost entirely around Jacob Tremblay. Review after review notes how expressive he manages to be beneath the prosthetics, earning laughs and tears without forcing either. Beyond him, the reviews credit director Chbosky with an understanding of how children behave, a generous spread of attention to the supporting characters, and a plea for kindness that most find persuasive rather than preachy. Julia Roberts, Owen Wilson and Izabela Vidovic draw steady if quieter notice.
The reservations are nearly all the same one: sentimentality. Even the admirers concede the lessons can be obvious and the emotional cues heavy-handed, and the mixed reviews find the message sweet to the point of repetition. The spread is wide at the bottom. The Guardian calls it manipulative and singles out Owen Wilson as a weak link, while Eye for Film finds it predictable but still rates Roberts.
