I like it.
'The Princess Switch' is basically 'The Parent Trap', but I felt it added a decent edge to it to make it suitably entertaining. I enjoyed seeing it all unfold, it's well made. I found the casting and pacing good.
I rate Vanessa Hudgens and thought she did a great job here, given she's playing a dual role; and practically has to act four different ways as Stacy and Margaret. She's convincing. There's not much happening away from her, I admit.
Cheesy Xmas vibes, of course. I dig it though.
