Doug Walker, better known as the Nostalgia Critic, became a cornerstone of internet culture through his high-energy, over-the-top reviews of movies and TV shows. His exaggerated facial expressions, theatrical screams, and iconic suit have made him a recurring subject for reaction images and video edits. Most famously, clips from his 2019 review of Pink Floyd’s The Wall—specifically the scene where he appears to scream in agony—went viral on platforms like Twitter and TikTok. These memes are typically used to represent extreme distress, sudden realizations, or ironic critiques of media, cementing Walker’s place as one of the most versatile reaction faces in the meme ecosystem.
