When I got this a long time ago, I absolutely adored it. The first thing you will notice is the excellent use of source material here, only narrowly defeated by Batman Arkam Asylum's effort. All the characters look like they do in the films and they are all voiced by their respective characters. The story is great and the huge variety of ghosts is just sublime.
The gameplay mechanics themselves are brilliant. The guns/ghost catching equipment are great and satisfying to use and the way you catch ghosts is clever and well designed. The level variety is great, although it is a shame the game is so short. This ties in with the poor multiplayer experience (Very little to do in it) to create the games only major flaw; there is very little replayability.
Nonetheless, many games are burdened by this problem and you may like the multiplayer, whcih would render this irrelevant for you. This is brilliant, fun, diverse, nice looking and deserved of a place in your collection!
