As mentioned before... all they have to do is get good writers, a good director, a good composer and a good cast and they could do one hell of a future war series of movies, if only they actually took the time and adhered to what Reese said all throughout T1 and not trying to make it different because "oh, people would be bored because they already know what happens" kind of idiotic logic.
Only morons think like that, because if that was so, then you couldn't make films based on books or plays or real events, because people have possibly read those, seen those or know about those too beforehand... so... with that logic, none of those should be possible to make. Yet... good screenwriters, good directors and good actors DO and make it entertaining and worth watching.
It's a lazy approach and lazy writing to not be able to make something people already know exciting. We know certain facts from Reese... yet, there are also so many things we don't know... and THAT's where the writers can inject their creativity... not **** around with established facts because... for whatever reason they choose to **** things up.
Someone who really burns for good story telling should be fed the facts established by Reese in T1 and he should then try to create a story from those facts... and seeing as things span over a long time period... it could even be as much as a trilogy of films.
T1 was a rather low-budget science fiction thriller... so a huge budget with loads of explosions and CGI is not the right approach for making this successful. We've already SEEN huge budget films with loads of explosions and they usually suck donkey balls and have no real compelling story or characters. The effects should really be secondary to the story and the characters... and the effects should go for quality over quantity - make the dollars count in a meaningful way - and approach the film from that standpoint.
I'd vote for Hans Zimmer to do the score, as he's the composer I think could bring back the Brad Fiedel feel to the score, seeing as Brad has retired.
