Haven't seen the trailer yet. Will do so this weekend I'm sure.
However, I did read the synopsis on Wiki. The short form of that synopsis (without sharing possible spoilers), it involves three different timelines, which of course that precedent was sent with the previous films. I.E. events in the subsequent films modifying events of the previous films...
I can live with that, as long as it isn't a JJ reset... and I like the explanation I read about how Aaahnooold can play the role despite the fact he is much older now than in the original fim. Won't spoil it though. Read the wiki if you like minor spoilers. Or the trailer may have spoiled that already...
All in all, I have high hopes this one will do OK. I really enjoyed the last two films, and Moon Bloodgood did well portraying one of my 'new' favorite characters in the franchise (Blair Williams). But then I'm easy to please as long as they keep it mostly interesting. Just as long as they don't try to pass off a beer factory as engineering!
On a related note, finally saw Expendables 2 and 3 this week (been holding out for a price drop in the video section at Walmart for 2, 3 hit the shelves this week). For those that like action, lots of guns and explosions without the plot getting in the way of the action too much,ii.e. the plot mainly used to provide a convenient excuse for lots of action, definitely a good ride! That Ronda Rousey has some moves (she's the current UFC champ)! If you are looking for a deeper experience, there are other franchises with much more intricate plots...
Admittedly, some of the one liners in the Expendables franchise were a bit too corney, but the whole Chuck Norris/Lone Wolf thing still had me chuckling! On a related note, I'm guessing that Sly and Jason have become very good friends these days, based on how comfortable they are with each other on the screen.
Plus, it's good to see Arnold, Wesley, and many of the other action icons we all grew up with showing us what we remember them most for - high octane action movies!
Back to the new Terminator, I'm not too worried about being disappointed... yet.
