Same, I also found Uncharted 4 to be the worst game in the series. While the interactions between main characters were great, the villain wasn't good and the lack of supernatural elements really took the fun out of it. I even like Lost Legacy more than 4. Though I personally don't think that Uncharted 2 is the best in the series, I hold the unpopular opinion that Uncharted 3 is the best.
I also thought that Overwatch was deserving of the GOTY win that year. It's a lot of fun, the first multiplayer only game that was ever deserving of GOTY imo.
The worst in the series??!! Have you ever played Uncharted 1? How can Uncharted 4 a game that is better in every single way, including lenght be worse than U1?
