Lomm, regarding
A Walk in the Woods -- I watched it again, while my internet was down, and actually liked it a little more on second viewing, probably because my expectations were low and so I was able to appreciate what good bits there were. But there were so many wasted opportunities to jazz up the story, particularly as concerns meetups with other people. For example, at one point they are entering a rest area where a lot of hikers are hanging out. Instead of stopping to talk/interact with some of them, they walk straight through and continue silently on their way. When they do interact with others, those encounters are usually brief, meaningless, and/or annoying. And I still had no idea where they were most of the time, or where they ended up -- even though I looked for license plates on the vehicles.

Plus, one would expect a journey like this to be a life-changing experience, at least in some ways. But it's not. He's the same guy at the end, who's just come back home from a very long walk.
If, after seeing this film, you watch and compare it to Reese Witherspoon's 2014 film
Wild, I think you'll see why that one is so much more successful.
