Terminal 1 isn't that bad. Sure, it isn't huge or flashy, but its efficiently designed and has a respectable amount of retail and food options. If anything, terminal 2 makes it look worse by forcing people to judge it as the "modern" terminal. Having the new terminals will make terminal 1 look better, imo.
Not that it really has anything to do with anything, but when I was a real little kid, I always got the ceiling of terminal 1 confused with the arch at the entrance to SeaWorld. I'm pretty sure the first time my family flew out of terminal 1, I asked my mom if we were at SeaWorld
