Don't let the offhanded comments get to you. Your complaints are valid.
I really wish they would've tied up Lee's past. It seems kinda wrong to introduce it as this huge plotpoint in the start of the series then completely forget about it near the end.
The campman storyline was terrible. Not just because of the plotholes and laughable motivation of the stranger, but because it could've been done much better than it was.
I wish TellTale will develop the entire game first rather than work on one episode at a time. Sure, it may mean waiting longer, but they wrote themselves in a corner with Episodes 3 and 4 and because of that, Episode 5 suffered immensely.
