My feminist take - Tyrion was a misogynist and the fact that he is portrayed as a one of the more heroic characters is worrying and an indicator of how blind we are to misogyny
Apparently there is a theory that Tyrion will end up the villain in ASOIAF due to his actions/nature and at this point in time, due to the nature of his narrative (his wit and perception etc) the audience side with him at the moment, and D&D took the wrong end of his character to run with ... after all, in the show he doesn’t become a bitter and twisted repetitive (“and moon boy for all i know”) sob!
I think there are a number of strong female characters, weak female characters- I think it is wrong to assert that Brienne and Arya are “men with tits”. Briennes POV chapters talk about how she suffered from being different from other women, that her height and strength have been something she has had to accept and work with - to the detriment of many things.. these are all things a woman can relate to (i work in a 90% male dominated physical environment and the desire to be STRONG to compete but also be seen as a woman is something i relate to).
Arya is developed well - many chapters talk about how she and sansa have a fractious sibling relationship due to arya’s inability to “act a lady” and her tomboy nature is well established, her love of Jon etc. Her becoming an assassin is an interesting opposition to what sansa does - she uses weapons as her weapons, sansa uses words - who were their tutors at the start? For Arya syrio forel and for sansa cersei!
I think any adaption from literature to screen suffers from simplification of many many pages of insight into characters ... as potentially the above shows
