I quite like them, at least the ones I've seen made in 3D. Gives some depth to the picture, if the film maker can resist doing the gimicky 'things flying out towards you from the screen' thing and just try to give some depth to the stage, a little like going to the theatre.
I've tended to stick to animated stuff such as Toy Story 3, were the filmaker seems to have more control over how it looks. Have to agree with the OP though - there is still work for them to do on the films and a poor movie in 3D is still a poor movie. What annoys me that there is a premium charge to see them and what seems like a ploy to get audiences to see films that they may have otherwise not bothered with, due to their quality/content by making them in '3D'. Go to see films you would have anyway and don't go to anything just because of the 3D.
(Actually I don't mind the inflated ticket prices too much as I do recognise they probably cost more to make)
