I am not against season passes on principle, but you should have a very good idea of what you are getting prior to purchase. I don't think it makes sense to pre-order a season pass. Wait until you have a much better sense of what the content will be. You may also find that the core game is all you ever want.
Season passes that made sense for me:
BF3 & BF4 - you know exactly what you are getting - a roughly quarterly drop of ~4 maps and the occasional new mode. If you like Battlefield, this is a reasonably safe bet. A little on the expensive side, but a lot of content over time.
Driveclub - this game is in reasonable shape nowadays, and the track quality is high. I'm happy to get more of it over time.
Last of Us - the single player story and multiplayer maps have been great
Season passes that I have a hard time justifying:
Shadow of Mordor - I platinum'ed this game, and I can't see paying 50% of the price of the core game for a few more story missions. Really hard to tell what you are getting for the money.
Anything Ubisoft - the season passes are expensive - $30 for Far Cry 4 season pass? The core game has a ton of content, so I'd rather attack my backlog then buy more Far Cry 4.
Alien Isolation - again, the core game was criticized for being a little too padded as it is.
