Here are some resources that really show off the beauty and community of the AT.
If you have Netflix... you should check out the National Geographic Special on the Appalachian Trail. It is not extremely informative but it does show some splendid aerial views of the trail. There is also another movie that is kinda fun called Southbounders. Southbounders is a dramatic film rather than a documentary. It is also more of an indie film so if you aren't use to that you may not like it. However, I say be adventurous and watch it!
Another option is to watch one or all of these videos made by former thru hikers. You get to see the beautiful views they saw through 14 gorgeous states.
And I will add this video that was recommended by the very funny Good Badger:
If you are more of a reader then you should consider reading Appalachian Trials, AWOL on the Appalachian Trail, or A walk in the woods. All three books shed light on what it is like to hike the trail in different ways.
For an in depth look at the everyday life I would suggest reading AWOL's book. For a humorous approach, definitely read A walk in the woods first. Last but not least is the Good Badger's book Appalachian Trials which is really aimed at a hiker more serious about trying to attemp the trail. It focuses on the emotional aspect and how to prepare yourself for success.
