If you were a fan of Deadly Premonition and you’re eager to relive the experience or view the new scenes, the game is absolutely worth a BUY. Likewise, if you’re a newcomer to the series, the Director’s Cut is the best version available.
If you hated the original, purchasing the game depends on what you hated: the controls or the story? If the controls kept you away from the original, the Director’s Cut is your chance to dive right in. If the story wasn’t your cup of coffee, you’d do well to continue avoiding this game.
