My biggest disappointment with PL was that the devs, Third Law Interactive, decided to create 3 short campaigns instead of a single decent length campaign. They made the mistake of trying to emulate the structure of the original AvP2 stand alone and as a result the expansion pack was diluted across 3 short campaign. They should have concentrated on creating a single new campaign for the Corporate Single Player. That would have fleshed out really nicely a quintilogy of Campaigns: the Marine, Alien and Predator for the stand alone; and the fourth, Corporate campaign for the expansion pack.
Most people agree that the Marine campaign is the best in the original box; so using the formula that made that successful would have been a great move for the expansion.
