'It's like RTD couldn't decide whether to have Jack and Ianto as an OTP type of couple or a totally fu**** up type of couple. He just took little bits from both types of relationship, leaving us feeling confused and unsatisfied.'
I think that RTD actually saw Jack/Ianto as a OTP. When he tries to write OTP the relationships are always screwed up, with one person having all the power (in this case Jack) and the other not having any (Ianto). Just look at Doctor 10/Rose
