While the first 2 are untouchable, I feel like Salvation and Genisys get unnecessary flack. Salvation may have not had the dark and gloomy aesthetic we've come to know from previous films, but it was still a pretty good movie. Genisys is no T2 but it's definitely more fun than 3.
Haha well honestly I was one of those who was really disappointed with the way Salvation turned out- so much so that it made me appreciate T3. I'm a fan of the darker, more serious apocalyptic route but that movie left a lot to be desired for me... I saw it only one time in the theaters- maybe I'll give it another chance though. Have yet to see Genisys but will probably have to now that I want to revisit this series.
