The very last thing the movie is going to do is return to "Present 1" - the post-X3 timeline - by the end of the film, when the decisions made in that film are the "****" Bryan wants to fix.
Again, you are agreeing with me!
You say "the movie can still work with someone traveling to 1973 to do something which can prevent a horrible future", but if they "prevent a horrible future" then the future is different than the one we started with!
Your second point is a bit confusing since you seem to be contradicting yourself. How can you first say the movie can still work with someone traveling to 1973 to do something which can prevent a horrible future" and then say "The film may keep the part where something in the past has changed, which then causes this horrible future. But they may not."
The whole point of Days of Future Past is that something in the past needs to change, either preventing someone (The Brotherhood) from killing someone (Senator Kelly) or something else from happening (like something being invented).
And again I totally agree with you that Bryan would want to change the garbage that we were left with post X3. And what better way to do that than to change the past which creates a brand new future in which much of that garbage never happened! For all we know some of the cast may be in the movie for only a couple of minutes.
Here is something else to think about...
Post X3 Xavier is dead, but we have all sen the pictures with him in an X uniform. I also thought it was interesting how he wasn't in a wheelchair!
For old Xavier to be alive (since he was dead at the end of X3) we must be in a brand new present (future). This would mean that the movie effectively HAS TO have something in the past changed in order to have a brand new (Xavier alive) present (or future, depending on your point of view).
For Patrick Stewart to be in the movie he has to be alive post X3. For him to be alive post X3 something had to change in the past thus creating a new present.
That is what Days of Future Past is about... changing the past to change the future!
So something changes in the past (maybe an inhibitor collar is brought back to 1973) which creates a new Sentinal controlled future (present) in which Xavier is alive! Someone knows that something is... "off" (Xavier) and uses another mutant (Blink or Forge) to send someone (Bishop) back to fix it (stop the collar from getting into the hands of the government, bad guys, whoever!). Stopping it ends up creating a whole new timeline (future/present).
So in this scenario the movie would go back and forth as follows:
Present 1 (Post X3)
Past (1973 - Someone being killed/something changing the timeline)
Present 2 (Sentinal controlled - Xavier alive - new character(s))
Past 2 (1973 - Someone from future (Bishop) coming back to stop it)
Present 3 (Everything put right, or better yet, Age of Apocalypse)
If you disagree that there will be at least 2 presents/futures then simply explain to me how/why old Xavier can be in the movie in the new uniform we saw in the promo shot?
