Handling the proton pack is as fun as it sounds. Not only do you get to shoot your own particle beam, but you can perform your own wanton destruction, and even make your own burn marks on the wall!
Taking down ghosts requires you to wear them out first before you're able to wrangle them in your beam. Once you do, it's a simple matter of wrestling with the ghost until it's over the trap to suck 'em in. And even that's not a guarantee - you need to keep them steady over the trap, or else they may wriggle free from the trap's beam, and you have to wrestle them back over it again.
While it' true that the "cast" is controlled by the computer, it never really feels artificial. In fact, you really feel like youakre working as a team. There would be times when there are three beams locked on one ghost, and it wasn't until I helped out that the ghost made it over the trap. Other times, they were okay fending for themselves while I was on my own.
The humor wasn't over the top funny, but was enough for the game itself to give me a chuckle every once in a while. The cutscenes weren't in the "uncanny valley," and sometimes were comparible to the movies.
Hey, to have a Ghostbusters game with all original cast members reviving their roles is good enough for any fan of the movies to purchase this game and play it at least once.
