My expectations were low when I saw it, I was dubious. I don't know there was some "self fulfilling prophecy" going on but I still felt rather indifferent about it even after watching the movie. I didn't set out to "hate" the movie but I was curious as to what everyone had been going on about. 

Can expectations alter your perspective about a movie? 

Yes. I was looking forward to Iron Man 3, had been following news and progress profusely for months and months (getting so hyped) and yet I came out of it, far less happy than I had intended to feel. It was good, I enjoyed it but it did not meet expectations and left me feeling a little void of something I had been looking forward to.

In terms of Frozen, if I liked it, I would be happy to jump on the bandwagon but instead, my curiosity had not been piqued as much as I had hoped and it ended up being a "meh" movie. So having an open mind is probably better than having any expectations at all. Had in not been for the outside hype for Frozen, I may have been able to like it without carrying a slight bias. Even so, the plot and characters would still be flimsy and who knows, I still may not be in love with it.

I wouldn't watch it again, there's no point to waste my time with a movie I don't like, when I could re-watch one I do. Emperors New Groove, Toy Story, Monsters Inc, Oliver and Company, Lion King, etc.

Be that as it may, I wouldn't try comparing Frozen or other movies to each other. They're movies but with plots so vast and tastes just as vast, it's like comparing bananas to crackers, they're all food but they make different people feel different things. It just seems unfair a bit.
