Groove is the perfect rave in the sense that it's not commercial, it's from the fringe by locals, there's no alcohol, it's small, and everybody is having fun. However, nothing is perfect and so the night goes...
The good. Excellent music. You meet almost every kind of raver. The characters are nice, well developed, and acted just right. Each scene has something special and represent a usual occurrence in a rave. You can feel the ecstasy taking hold, and you can live the tracks as if you were dancing the floor. The dialogs, interactions, actions, reactions, settings, and costumes are very realistic.
The bad. Nothing.
The ugly. Nothing.
The result. If you've ever experienced a rave, after seeing this, you'll be looking for your next one.
