It's not perfect, but I cant give a reasonable answer to the other extreme of an opinion. fwiw, as a researcher I spent quite some time on this paper, but that subjective point doesn't mean anything to you.
I've read hundreds of ML papers, and this one is better than 90%, maybe even 99%. It's one of the best papers published in 2012. The authors are some of best minds in the field. Statements like "It is not even considered a good paper", or "very weak" need some explanation, to say the least.
The only negative thing I can say about that paper is they have not open-sourced their code.
