Rate the seasons of MNiE (tl;dr - Seasons 1+2 awesome / S3+4 crap)
Season 1 - 9/10
Season 2 - 8/10
Season 3 - 4/10
Season 4 - 5/10
The reason why I've rated Seasons 3 and 4 so low is due to the poor writing the episodes had, Earl didn't do his list and instead spent time doing either time in prison, chores for someone or in dream sequences. Plus, let's not forget Season 4 ended with a cliffhanger "To Be Continued".
And they never stated who's the father of Dodge and Earl Jr.
