It is a masterpiece! Amazing fantasy movie for anyone that has no idea what Dungeons & Dragons or Forgotten Realms are. However, if you are reading and playing them for years, it is a delight the amount of details and references within just two hours. Every creature, every location, every mention, it is just incredible. You can feel the dedication on every detail.
Again, no background on any of these are required, the movie is extreme fun and entertainment from the beginning to the end within a world rich both in history and in fauna.
However, whoever is like me, someone that had been playing since TSR era, it's just formidable to watch D&D getting into the mainstream that big. Audiences will be delighted!!!
