Having watched and enjoyed all the series to date (although I preferred the earlier ones), last week I finally bailed. For some reason I just couldn't sit through another episode - it was like groundhog day.
I think a lot of it has to do with the Maitre D'. The rot started in the previous series when he took over, and now it's beyond annoying when we have to hear him spout the same pseudo-philosophical, repetitious drivel every episode. I also don't like how he (and increasingly Cici the waitress, who I really fancied before) gate-crashes dates and inserts themselves into the story.
I'm surprised Cici doesn't carry with her a portable spotlight on a selfie stick. She was totally over the top when she basically hijacked the date between the two gay guys a few weeks ago and caused one of them to feel really bad.
It's interesting that in the comments here during the last series the Maitre D' had a lot of support and people generally liked him (especially the female posters) but it looks like the tables have turned, judging by the comments this series.
I think the insertion of the staff into the narrative has spoilt the show, but also I hate the lack of follow up. It leaves me feeling frustrated at the end as we don't really know what happened to any of them, and if people appeared to really click it's important to know how the story ended.
