How dare they pretend that "Monte Carlo" is a new movie idea?

Now, my friend brought it to my attention that it is the exact same plot as the Lizzie McGuire movie, i realize that movies are redone all the time but why would producers think it would be okay so close together what was Lizzie McGuire was in like 2004 so wth or was it 2006 well anyways what are they trying to do, and yes i do realize that it happens but why are they making the same movie with just different people why won't anyone come with a fresh idea. Shaking my head.
