Unless you are a die-hard fan of the show, the only reason to go after this is a platinum trophy that doesn't require a significant investment of hours. The progression of the game is incredibly slow, in-game navigation between locations and menus is clunky and unsophisticated, and the tasks required of the player really don't change as you work through the five chapters/episodes. Basically, once you've worked through the first chapter, it's just more of the same for the next four.
Unfortunately, the game doesn't really have any redeeming features to get past these flaws. The story isn't the slightest bit engaging (the slow pace of the game shatters any opportunity for it be so), and despite having got most of the cast from the show to lend their voices to the game, the voice acting is, for the most part, abysmal. The character voices are all recognisable as those from show, but the delivery of the dialogue is incredibly flat and wooden, and you really get the impression that none of the cast were really interested in being there.
Get it for the trophies. Otherwise, it's probably prudent to steer clear of this.
