Cameron shouldve made T3 instead of (or as well as?) the 1996 T2 3D theme park ride - hell he built the future war set for that (including skynet HQ) would've worked wonders for a future war T3 - plus everyone was still young! no need for CGI deaging (maybe there could've been an opening 15-20 minutes with John and Sarah present day before the bombs drop in 97. then it goes to 2029 in the last days/hours of the war with Biehn as Reese, Michael Edwards as Conner and eventually Arnold as multiple T800s, and RPatrick as the T1000)
Basically Cameron couldsve just beefed up his discarded original T2 future war opening as described in T2 novel & Illustrated Screenplay book (also seen in the comics All Our Futures Past & Cybernetic Dawn/Nuclear Twilight)
Then like original SW/Indy, BTTF & LOTR, Terminator would've been this unbeatable trilogy (1984/1991/1996) instead of this fractured mess of films with 3 failed T3s and 3 failed trilogy starters
