-.5 because the plane controls are very BAD. Trevor, I dislike you for forcing me to pilot a plane for like at least five of the total missions in this game. Making me use the worst vehicle ever fits his character though.
It can be pretty dumb at times, but I ended up really liking the goofy world this place had set up even if it's filled with a ton of David Cagisms. Hank and Connor's chapters at least make the game worth playing.
