What's the consensus on PSL? (The Party for Socialism and Liberation)

Before discovering this community, I was in a different community that proudly calls itself leftist. I posted a documentary; Loyal Citizens of Pyongyang which was very eye-opening for me.

Anyway, posting that started to really upset people, saying that the documentary is PSL propaganda. That PSL is authoritarian, backed by a Chinese Maoist billionaire and that PSL is riddled with sex abuse scandals. That of course PSL would simp for DPRK because it's authoritarian. I was even called a holocaust denier for defending DPRK.

So is PSL bad? Where can I find better information on this? I've already tried looking into PSL and it all seems okay? The sex abuse scandals I am not sure about, is there more information on this? Am I being too critical on this?
