Did you get the feeling that... (spoilers... kinda... but kinda not...)
Did you get the feeling that the kid Gary, was in a sense Joe as a kid and would Joe not have met Gary and helped him out he could have very well have been ended up being Gary's father G Daawg? (metaphorically)
It just felt like that watching it, Gary was the young and innocent, and his father G Daawg was the complete opposite; a terrible piece of sh-t, an Joe was somewhere in the middle; a troubled person that made alot of bad decisions but still had enough good in him to not be a genuinly bad person but could go either way
