Plot Review:

Plot was a bit slow in the middle but not so much that it became uninteresting.

Character Development:

Thought Marty McFly was very interesting but would have liked a bit more character arc.

Setting:

Understood the setting but could have used a bit more detail to make it more real.

Grammar, punctuation, etc.:

All fundamentals seemed sound. Think there was one small misspelling in 2nd paragraph.

Dialogue:

Loved the inflections!
