How to avoid using the new Photo Viewer on Facebook.

This week Facebook rolled out its new photo viewer application/interface and since then there are a lot of negative comments I have come across from users about it. I personally feel its quite an improvement from the previous viewer which for me was a bit slow and the view window was kinda small. Overall I like the new photo viewer also called "theater". It pops out, lets me focus more on the details of the photos than on the surrounding because of the dark background, I can resume viewing updates from where I left just by hitting the close button on the top right. In fact Facebook now stores the photos you upload in a much higher quality compared to the older times. They have increased the size of the photos stored from 720 pixels to 2048 pixels which is high quality. I don't really understand why people these days always complain about anything new on Facebook.
