Meh.
I’d gladly pay $50 at the theater with popcorn etc for the single viewing.
I will not spend $35.99 to watch this movie in my living room over and over.
I find this always to be an interesting topic - the value of watching a movie in a theater versus at home. Suffice to say, I think people are very varied on their opinions on this (not to say any one opinion is right or wrong).
For me, I get a lot of value out of a theater experience when it's a big event film and the crowd is really into it and hanging on every action (e.g. Marvel, Star Wars type stuff with fanatics). But a movie like Mulan wouldn't really have that kind of in theater experience because even if people enjoy it, I don't think there will be that kind of excitement "in the air".
I'm pretty indifferent in the big screen/sound versus watching on my flat screen at home. Sure, the theater is "better" but not enough for me to care; many people are strongly disagree with this I know.
So, my main reason to ever go and see a movie in the theater is: (1) to see it as soon as possible [especially in trying to avoid spoilers for popular films] and (2) to enjoy a big crowd experience. So, for Mulan, neither of this apply and I'd actually rather pay $30 for my family (I already have Disney+) than go to the theater and spend more. at least we can watch at our convenience and have food and bathroom breaks and rewind/pause/whatever to our liking. YMMV.
I think the most interesting thing is it being D+ exclusive apparently and not able to be rented through other services. the price is pretty much what I'd expect for it to stream at home.
Also, is Mulan going to get a theatrical release in other countries where the theaters are open?
