The ending we didn't want or expect.. AKA oof, that was rotten

..and before you get into all that "reality" crap, it's a TV show, it's not a documentary. They could've taken some liberties. I don't want to watch a show to tell me what happens in real life. I am watching to get away from real life..
The ending kind of ruined the show for me (or, at the very least, the whole of 3rd season). They build up the whole of the 3rd series for..that..

I will watch the movie, but that came out almost 15 years after the show so I'm glad I didn't watch it back then or I'd be very very pissed off, investing all that time only for it to end as underwhelmingly and disappointingly as it did..

PS. I did find the rest of the series really good. But this.. "not like that"..
