I'm sure most people are familiar with the situation that when you look back at works of any kind (writing, art, crafts, whatever) that you finished some time ago, you come across one for which you still find the idea/concept really awesome, but now you kind of cringe at the technical execution, or at least some of it, because you've gotten better with practice since, and if you realized the same idea now, it could have been so much better. And while you still know that you were really proud of it then, and still love the concept behind it, the less accomplished realization now almost seems like a waste of a great idea.
And then some people may redo their old work if they find an idea compelling enough, i.e. rewrite that old novel in a second version, redo a painting, etc., while others may revisit similar themes or mine their old work for ideas, but don't go back to finished things to do the same thing again, just better. Personally I'm in the second "camp" and don't think I've ever done a remake version, but I wonder how others feel, thus a poll:
