Sequiro: ...
Sorry for the long winded rant, but I was a bit annoyed at some read reviews.
I can completely understand you. The standards are way out of balance. In principle there is nothing bad about a release of a game of any quality. It doesn't make the releases of better games more or less likely or makes the quality of other games higher or lower. It just doesn't matter at all.
However I can understand if somebody is frustrated by a release of a buggy game. There I am a bit on the extreme side and I rather had they would not release buggy games at all. This only creates frustration on the gamer's side.
Also if it's a bad old game, you can surely, ironically, express your opinion or give a low rating. After all, others can choose to ignore this opinion. Not every game has the same quality. Some are really bad. Gothic 3 is an example. Totally unbalanced. MoO 3 is another example: contains as much fun as a tax declaration.
