Let's look at what it ACTUALLY got

Quick look shows that it generally averaged high 80s, low 90s with a few very negative reviews. Which is perfectly reasonable. It had a few technical flaws, but they didn't detract from the gameplay as far as the actual gamers were concerned.
PS3 and XBOX did a lot better (about 8 points) because of THE EXACT PROBLEMS YOU LISTED!!! Maybe, rather than just reviewing review sites without actually reading them, you should try to actually review what is actually there, not the hype you heard about on the radio. Either that or we all have to assume you are an evil person who works for a consortium of people who are opposed to game journalism (because that is CLEARLY the only reasonable conclusion :p)
Wild sweeping conclusion (I'll give it a shot, since you already made a bunch in your post): The system isn't broke. Some review sources may be suspect, but that's why you don't go to "Cheat Code Central" for a game review.
The funny thing is, I used to subscribe to EGM and Official US Playstation Magazine (both had the same publisher, I believe). More often than not, OPM was MORE critical of PSX games than EGM was. Never really understood how that worked
