The original Mad Max has aged terribly and is completely inferior to Fury Road.
On that note, Fury Road is the best installment.
Terminator Genisys is a perfectly good film and a great (and so far only worthwhile) third installment to the franchise.
The Expendables films are good.
Game of Thrones is good, fun, and a neat show, but I don't think it's great. Still above average.
All video game adaptations should be HBO/Showtime/Amazon/Netflix shows instead of movies purely based on the logistics of translating 15+ hour stories to 2 hour films.
