It's very rarely worth damaging your career prospects by picking a fight like this, especially if the other side has good standing in the research community network with powerful allies. I understand the romantic ideal of the hero uncovering bad science, but there is just too much mediocre research out there to spend energy on. Peer review is supposed to catch the biggest errors, but it's very imperfect. After that, only huge landmark results may be worth attacking, because there will be a bigger audience who will be interested in the truth. If it's a niche thing, nobody will care and you just hurt yourself by not focusing on your own work and by making enemies.

What people typically do is just to ignore bad research, and withhold praise, and do their own research in a better direction.
