I don't think Tiana's a kill joy, she just likes to work hard. That's what I like about her.

No she is a hard worker and very responsible...Too bad there are not more teenage girls like her. She is a great role model and an inspiration and she has more important things to do then be irresponsible.

No; there's a difference between a killjoy, who is someone who ruins fun for the heck of it, and someone who plans for the future. Tiana is the latter.

No, Tiana has lots of fun too but she doesn't show it.

No! She's just spent so much of her life focusing on her and her father's dream that she kinda forgot how to have fun, and how important it is. Good thing Naveen came along to remind her what real fun is like.
(That last sentence doesn't sound too suggestive, does it?)

No, she's just ambitious and a hardworker--far from being a killjoy IMO.

She works hard and is responsible, but she can have fun at the right moment...

never saw this movie

She's sassy!

Just because she's determined and a hard-worker, it doesn't mean that she's a kill joy.

She can be towards Naveen but I can't blame her for it anyway. But other than with him, she didn't show it. She just prioritizes.

In the beginning of the movie.
