very large man sitting in middle seat exit row. He took up 15-20% of my seat with his arms, shoulders, and leg for the entire flight and was resistant when I nudged back trying to reclaim my personal space. This resulted in an uncomfortable ride using only a fraction of the seat I paid for. I feel like I did not get the full use of the seat that I contractually should have been provided.
