The thing is, you don't practice being a live TV presenter on Saturday/Sunday night primetime TV! But that's what these two are effectively doing. Caroline has been a reasonably adept presenter on other shows, but XF live is a different thing altogether, and she's not rising to the occasion. Ollie is so green at this he's practically Kermit! Again, expecting him to look like Dermot or Ant'n'Dec was a bit of a stretch and he's just not anywhere near ready to be presenting one of ITV's biggest shows. Also, what was with Ollie and Harry Styles - that was a very specific snub from both ends I saw there?! Was this about the whole Harry-Caroline exes thing?
I agree with those who say that Ollie's mistakes and nervousness seem to be infectious, and Caroline spends the entire show visibly jittery and worried looking. Neither of them look like they're enjoying this, it's just so uncomfortable to watch. It definitely brings into sharp focus how hard live TV actually is, and just how effortless Dermot made it look!
At this point, it would be a blessed relief to have someone else present, but that would be the final admission of failure for Simon, and he won't do that. So Ollie and Caroline will probably continue to be bollocked off-screen, leading to even more nerves and mistakes on screen! Last night was so bad my mum was actually in hysterics, laughing at the terribleness of the show! I've got to think that this was a reasonably common reaction to what was going on.
