Recommending a paper rejection

A person I know recently asked my opinion on a paper which she was reviewing for a journal. I gave "outright BS" flag that I deserve for unique occasions. She then told me that she held the same opinion and wanted an independent opinion. She was going to recommend outright rejection. (we work in different institutions, studied different curricula in different universities, without a single common professors. Therefore, there should be no risk that we share a common bias due to a common background formation)

There were way too many deep methodological errors, and it was all based on a recent small fad that has already been dismissed. Anyway it came from a group in one of the super-top universities in the world (yet that paper did not have any famous name in it). 

We get a couple of rejections from time to time therefore we know how much it sucks when you get rejected with the feeling that one of the reviewers did not even understand your work. Therefore, we try to avoid rejections if we don't feel totally sure that there's something wrong. (if it seems wrong to us but it's not really something we are experts we suspend judgment)

Anyway, it turned out that the associate editor and the other reviewers not only were positive, but were even complimenting the authors for their "perfect" paper. It's so awkward writing: "it's totally wrong" when other are saying "perfect". And I know that it's terrible to get such mixed reviews. I got them a couple of times and it felt like: "why didn't the editor beat the crap out of that ignorant dork?". Yet in this case it seems totally scientifically justified to try to keep preventing publications at all costs, if we want to maintain our integrity. 

How do you deal with this? Did it ever happen to you to be "that reviewer" that would recommend rejection despite the others being favorable? What do you think about when it happens to you as the reviewed person?

I would be very specific about why it is wrong, with citations. It is possible that the editor and other reviewer are a bit too far outside their expertise, and overlooking some of the flaws you've found. A detailed review will help the editor and the authors both, even if it eats up a lot of your time.
