I think the series actually did a good job highlighting the number of ways in which men are in control/take the piss/make it all about them, let alone the violent crimes some commit etc.
The weak spot was Trish agreeing to ex coming round - I thought this jarred, and was out if character for Trish - we saw her stand up to Kathvwhen cornered, even though she was also in the wrong (having slept with Kate's dh), so I don't know why the scriptwriters chose submission at that point.
Otherwise, I liked the symmetry of seeing Beth and Ellie at the end - laughing, happy with what's left of their families, which mirrored how we first saw them in s1 I think - 2 families, getting back in track.
I think the series was actually very good at not 'just' highlighting how awful rape is - there was a shitload of other dodgy behaviour, from just about every male character in it, and whilst it was highlighted to us as viewers, it was also shown to be just part of life (as it so often is). A true mirror. If all the dodgy behaviour had been tackled, then there would have been a lot more 'but not all men do that' defence - but this way, with each man having something unsavoury about him, but also shown to be human, I think it highlighted more just how much is accepted by society as a status quo.
