Good question. I think a part of it is that I enjoy a very high percentage of the movies I watch, because if they don't interest me at all I don't watch them. I kinda slowed down on the classics and I can't really think of any that I didn't like. I guess maybe Lawrence of Arabia.. It wasn't bad but it was incredibly boring to me. A well reviewed movie from last year that I didn't like at all was Carol. I didn't enjoy that one on any level.
I guess I also usually agree with critics and maybe it is my love for the genres blinding me, but I legitimately don't think BvS or Warcraft are anywhere near as bad as their RT ratings would suggest. I do admit I came out way too hot for BvS, I was trying to counteract all the negative reviews calling it complete garbage. I think Warcraft is better than BvS.
