Answer

Region and style have a lot to do with a question or sentence being 'correct'.

Isn't that what you wanted all along? or Isn't that what you have wanted all along?
--Either are 'correct', but adding the word 'have' makes the question a bit more formal.

It wasn't good from the start. or It haven't been good from the start.
Correction--It hasn't been good from the start.

Answer
