Time travel paradoxes have always been an issue for the series, but this one was just a total mess. Plus, digital Arnie looked like an action figure. Without spoiling anything really, I think the biggest winners from the events in this film were Sarah's original timeline roomie Ginger, and her boyfriend.
Biggest winner was Sarah Connor who got an upgraded Kyle Reese lol. Jai Courtney's body, oh my.
I don't quite understand the general audience/critic reaction, it seems like people had a pre-determined notion to not want to like this movie, or maybe just had a very different set of expectations than I did. Honestly I enjoyed it quite a bit more than Jurassic World, and the audience I saw it with all clapped at the end, which hasn't happened in a long while.
I actually thought it was a clever use of the characters, and while maybe the time paradoxes weren't all that well thought out, I really didn't care as I had such a good time. I felt Emilia Clarke did a nice job taking a different approach to the Sarah Connor character; keeping in mind this was supposed to be a very different Sarah with a very different personality than either of the Sarahs we've seen in T1 or T2. The weakest part for me (but also a bonus in other ways) was having a Kyle Reese that was a little too hot and buffed and sexy (sorry Michael Biehn). Like am I really supposed to feel sorry for Sarah that she has to do it with such a freaking hot stud lol? He looked like a renegade from Magic Mike XXL lol.
