She needed to go. From the very beginning, when Holly replaced Fern Britton, I just felt she lacked something. She certainly didn't seem to have the emotional depth to tackle some of the more sensitive issues on TM. I found her and Phil together unbearable and gave up watching. Just too smug and self-satisfied. Their egos took over, and everyone's right-'Queuegate' and their entitled status as the ITV 'power couple' did for them both. They should have known. We build people up, here in the UK, to tear them down if we think they're too 'in your face'. The trick is keeping a lower profile when you sense that's about to happen. They arrogantly tried to ride it out.
Just to clarify, if the 'kidnap' thread story pans out as badly as it seems, it's horrifying and nobody should have to face anything like it in the course of their 'work'. I think both of them need to take some time out and find some grounding away from TV. Life isn't all about fame and money. Lots of people often learn this the hard way. Maybe Holly can come back, eventually, having matured somewhat, because I get the feeling that she never really did.
For each of them, it was probably good when it lasted, for the most part.
