Not dead but definitely on life support.
Boro - too late to resurrect and the apartment is crappy. Ivo and Sonia were washed up when they left the old Tula and have been decaying ever since. Nick and Lisa had potential but too many fights and not enough passion have doomed them to oblivion. Also, Ivo, Anex and Nick should have been expelled over the Nikita/Zoe incident and have been freeloading ever since.
Tula - Why the fuck did they ever bring Alex and Anna back from Sophia, they died in Bulgaria and should have been buried there. Anita showed promise when she arrived, but she never found a partner. I think she could still contribute if she were with the right man and in the right apartment. This apartment was a failure from the start, what sense is there in having a one bedroom apartment?
Tver - was the best of the bunch until Zoe and Jack departed. Apartment is well set up for partying and two couples can interact without being too confined. Lex and Iris can't run the show on their own but are great with another couple. Carmen is a lazy cow and the piledriver isn't the right partner for her, too aggressive..
Sophia - grand disappointment. Bella was full of life when she arrived, but then spent two months rotting in a superb facility. When Lou arrived, the life was sucked out of the apartment and her. She has a "settle for" man and has lost all enthusiasm and passion. Nastya started out on life support, came around and exploded with the boyfriend and then died when he vanished. Although it is the gem of the apartments, it is too isolated from the rest of the project and needs to close.
Bottom line, three of the thirteen members worth trying to resuscitate and one apartment.
As I say not dead but fucking near there.
