A great adventure that offers the players lots of choices.
The good: A globe trotting adventure that takes the players to 6 different countries across the world. An adventure that leaves the players complete freedom on where they wish to go and what they wish to do. Quite a few red herrings that receive just as much detail as the rest of the adventure giving the adventure a far more open feel then any comparable adventure. The investigation is well thought out with lots of clues and options meaning that no clue is so essential that missing it derails the adventure.
The bad: Call of the Cthulu is in general more deadly then most other game systems and Masks is even worse about it. It is quite possible that the players could suffer a total party kill/insanity even after doing everything right.
