This is my first time actually playing through the campaign and I enjoyed it. My biggest criticism would that driving to each destination before starting a mission did become boring and repetitive after a while. Sometimes I just wanted to skip all that and go straight into a mission. Though, I feel I would have liked it more if I didn't already spend hundreds of hours on GTA Online, where 80% of my playtime consisted of just driving around. So it could just be that I'm burned out on it.
Overall, I thought the story, characters, and missions were all pretty good.
