Fabrique des Lumières sits in the old Purification Hall of the Westergasfabriek: a raw, high industrial space that seems made for grand projections. With Prehistoric Planet: Dinosaurs, that hall becomes one gigantic screen. You don't walk past a row of signs, but through landscapes where dinosaurs move around you - from dense jungle to open plains and deep blue sea.
The power is in how close it feels. Because of the 360° projections on walls and floor, you don't get a "watching a movie" experience, but a "being there" experience. This works especially well with species you normally only know from pictures: you only really see what "gigantic" means when a neck above your head slides through the image and the sound breathes along with it.

The show is also cleverly constructed for different ages. Kids have plenty of action and recognizable "wow" moments, while adults linger on details: skin textures, lighting, the way environment and animal move together. You don't have to know anything about dinosaurs to like it; it's an experience rather than a lesson, with enough context to make it not just "picture looking."
You come in for the dinosaurs, but you stick around because for a moment your brain believes it's real.
Practically speaking, it's nice that Fabrique des Lumières usually works in time slots and that the dino-show sticks around an hour - long enough to get into it, short enough to stay relaxed even with kids. And because the hall is kept dark, the projections really pop: fewer distractions, more focus on the image and soundscape.
When in doubt between "museum" and "outing": Prehistoric Planet is clearly a museum-quality outing. Ideal for a free afternoon, a rainproof weekend plan, or if you want to bring someone along who normally doesn't warm to exhibits - this is more "experience" than "exhibit."
