We're so bounded by time, by its order.

This is the first superhero movie to actually dwell into the darkness that haunts the lonely, it tackles subjects as the likes of depression on a surface level of course, but it tackles them. They address how hard it is, survivor's guilt, PTSD, you name it. This is a solid MCU movie and I think I'll rate this one 5 stars when I do my marvelthon this year. It's at least in my top 5 MCU movies and honestly? Probably top 10 superhero movies.
I'm not saying the movie is perfect, it has it's flaws obviously. But so does everybody.
