1. Yes. Prolly not as awkwardly blunt as T2, but there will probably be something. Hollywood producers haven't realized that films no longer need the shock-value stuff to succeed (see: Pixar, the most consistent studio in the business).
2. With Hollywood's franchise craze at the moment, it'll keep going until one flops. But it may not continue with Michael Bay... he seems tired of them.
3. No.
4. T1 - 6. T2 - Never saw, but from what I hear, a 2-3. But this is from someone that has The General as a standard to measure films by.
5. No. It very well could be good if well written by someone with reasonable moral standards.
