There are two big factors why I can't like Chrissie anymore. First is obviously Lachlan, and while she at first dealt good the Alicia situation (after she realised that she was telling the truth of course) and made Lachlan face the consequences of his actions, she kind of dropped it later and always excuses what he does with a little slap on the wrists. And the second one is that after all that she threatened Rakesh with claiming that he sexually assaulted her, that was super disgusting.
And they are good enough reasons, people shouldn’t have to keep justifying themselves as to why they do or don’t like certain characters. You don’t like someone you don’t like them, you’ve got your reasons. People need to accept that and move on.
