Good watch, could watch again, but can't recommend unless you just really liked the first one.
Of all the boring premises, a legal requirement is a really boring choice. Forcing a marriage is not only not relatable for America (Mia's country of origin), but also not exciting to watch Anne Hatheway reject guys and have to settle. And all the while they ignore the obvious solution.
There is a lot of fun with the idea of a American princess just having fun with a lot of resources, and touching bits with her using her power for good.
Sadly, again, the movie doesn't feel like it does anything special, despite all the "pizazz" they layer on.
Again, it's good, but it is weaker than the original, and unless you have the background of that movie, you're not missing anything by skipping this one.
