I know what you mean Katiestar, I have always had an uncomfortable feeling about the whole thing. I don't want to rehash it all here, it's been done to death. But just little details, such as the amount the group admitted to drinking that night (total piffle) we could easily get through double the amount they said (not sure but I think they said about 1/2 a bottle each) during a meal out on holiday.
I am not sure that the friends have covered for the McCanns as such, perhaps they do believe them, but it's all so holey. I think a tragic accident occured and looking at that doco I wonder if it happened much earlier in the evening. Amaral said that the bed appeared not to have been slept in, but cuddle cat was in there. Maybe she drowned in the bath...who knows I am making it up as I go along.
The other perspective is that Amaral has to cover his back, and perhaps that's his motivation to write the book and make the film.
And it's very hard to know what to think or believe.
I agree about the dogs though, hard not to trust their instincts.
