The overseas market is making up a more and more significant impact on such. 10 years ago, it was barely registered. Now it's making the difference. Die Hard 5 did poorly here ($67m domestic total) but it made another $240 internationally, so we'll likely someday see a 6th.
*Sigh* I genuinely hated
A Good Day to Die Hard. I fell asleep while watching it IN THE THEATER! It was so horrible and so few people I knew seemed to be even aware of its existence, let alone seen it. I was really hoping it had killed the franchise for good. Anything is possible, so I guess
Die Hard 6 might still somehow salvage things but Bruce Willis seemed totally past it in the last one.
IIRC,
Pirates of the Caribbean: On Stranger Tides also did lackluster business here but made huge bank overseas. Ditto with
Underworld: Awakening. So I guess we have dem darn foreigners to thank for keeping franchises going even after later sequels seem to hit rock bottom. (Although, I am admittedly cautiously excited about
Pirates of the Caribbean: Dead Men Tell No Tales &
Underworld V. So, thanks, I guess.

)
Getting back on track, while I'm not crazy about
Terminator Genisys, I do hope we get
Terminator 6 just so that it can explain a bunch of the lingering questions from this last one re: Alex and who sent Pops back to 1973. (I'm guessing it was Sarah, or even perhaps Pops himself.)
Plus, unless I'm much mistaken, I think Paramount probably re-shot the ending for
Terminator Genisys so that Pops could survive for future installments. It would be a shame to waste those re-shoots if he's not going to come back anyway. The Pops/Sarah/Reese scenes were the best part of the movie, so I would be up for more of that.
I subscribe to HISHE and Honest Trailers. Also, if you haven't, you might want to check out Cinema Sins.
Honest Trailers are almost always great. HISHE can be hit & miss, although they did great stuff with
The Dark Knight Rises, Spider-Man 3, & all the Superhero Cafe stuff. Cinema Sins is a bit too nitpicky for my taste. I only watch it when I truly despise the movie they're ripping into anyway (i.e.
Prometheus or
Star Trek Into Darkness).
BTW, 6 years ago, HISHE used
Terminator to give us the greatest crossover of all time!

I ignored that stuff and was pretty much on board all the way (even when they were inventing time machines in the mid 80's) but as soon as Connor showed up in the hospital and that whole strand took over, I seriously started to lose interest. Sure enough, after his reintroduction, the film just becomes lots of explosions and set pieces that amounted to nothing (Arnie dives out of the helicopter to stop Connor..,...but actually helps him crash in the exact place he wants to be......oh for goodness sake).
I went in with low expectations but I was pleasantly surprised by the first half and thought there were quite a few interesting ideas being explored but when Connor shows up, the whole thing just descends into standard blockbuster tedium.
Yeah, that's kinda my reaction to it too. I think part of it is that the upgraded John Connor just seems TOO powerful for anything else to feel plausible. If his nanites can turn humans into Terminators, then why didn't he just do that to Reese & Sarah the first chance that he got? Why does he have such a hard time putting down Pops even though he's just a broken-down T-800?
Reese's quote is:
It had no choice. Their defense grid was smashed. We'd won. Taking out Connor then would make no difference. Skynet had to wipe out his entire existence!
As I said he has no idea what happened after he entered the time machine. There is nothing to say Skynet didn't have a backup somewhere else.
T3 also implies this. I got the impression from that film that their victory in 2029 wasn't as complete as Kyle Reese first believed. Skynet was still around in 2031 and they sent a new T-800 to Resistance HQ to kill John Connor. It succeeded, but was then captured, reprogrammed by Kate Brewster, and sent back to 2004 to stop the T-X and make sure that John & Kate survived Judgment Day.
