Having experienced the gay scene from the inside, I can tell you that it's unfortunately just like in the show: everyone sleeps with everyone else, fidelity is a dirty word, friendship is a concept, alcohol flows freely and drugs are all too easy to come by.
The series can't be faulted for its desire for hyperrealism, and in that sense it succeeds. But we're not here to watch a documentary, and Only Friends doesn't have the stature of an Oscar-winning film, so a little levity would have been welcome. The characters are in 100% toxic mode at all times, and we'd have appreciated it if this had been softened by a bit of a bitchy moment. I was expecting to watch this series all smiles with a glass of wine in hand and found myself sighing and thinking "someone get them a psychologist!".

Apart from Sand and, to a lesser extent, Nick, the characters are not really likeable: Mew is falsely candid and rather bland, Top is infuriatingly "I want to control everything", Rey is ultra-toxic, Boston is the epitome of the well-built bitch who doesn't give a damn about anything, Nick is touching but goes too far in his actions. Then there's poor Sand, in whom I kind of saw myself.

As for the acting, Neo and Mark are excellent. As for the others, it depends on the moment.

In conclusion, I'd say it's a good series, but if you have to compare it to Friendzone, which is in the same style, Only Friends is worse.
