I actually studies movie theater business for my thesis in Bschool so I can answer that!
It's going to be tough. Even places that are reopening can only do so at 25%. Even before COVID the margins on ticket sales are so tight that theaters stay afloat specifically on what's called percaps, or how much concessions they're able to sell on average for every ticket sold. Due to people sneaking stuff into theaters, or just not buying snacks, a good theater has a percap of $2, bad ones are around $0.50-$0.75. That means that one of two things will need to happen in the immediate - concession prices go up, or ticket prices go up. Neither of these will be regarded positively by theater goers which will lead to even more rejection meaning movie theaters are kind of stuck. The only relief I see is if studios lower the rental fees or take a smaller chunk of the BO, but there's honestly no way I see that happening now that they've seen how much money they can make by simply uploading their movies to iTunes. Remember this means they save on printing physical prints, or transferring digital to the projector drives, and shipping.
Of course none of this matters when you consider that there are currently no movies slated for theatrical release until the fall. Theaters might be open, but they're not going to be showing much.
All in all it's not going to be a smooth ride for movie theaters unless they crack some code that makes theater experiences unmissable. This has happened before with the advent of 3D, 4D (that thing where they just spray water in your face), drive-ins, and dine-ins. Anything that expands beyond, buy a ticket and sit down will help but unless they have that in their back pockets it's going to be a long time until we see anything like that.
