I guess you have some points. FWIW, main characters are thugs, of course you’re not supposed to like them. The only character that is sorta likeable is Franklin, Trevor is too odd for me and Michael and his family are annoying AF. But I do like the way it was written and the humorous / epic moments. It could have been better yeah but I’ve played through it a few times now and it’s always been enjoyable.

Compared to 4 which I replayed recently and was pretty bored halfway through.
