a long time before russia intervened directly to try and fix the bullshit usa and their allies started.
how exactly is helping Assad bomb hospitals (okay admittedly coalition forces have hit a hospital or two as well), using chemical attacks on civilians and starving whole cities with siege blokades 'fixing bullshit' ?
When you have important generals hiding in school and basements of hospitals or are using infrastructure around hospital on purpose, when they are using ambulance vehicles for transport of troops and similar, expect to be hit a lot. Chemical weapons are constantly used by rebels that US supports, so don't see any difference there. People in a war will use what ever they have to survive. There is no starvation or blockade of whole cities, as there is constant transport of food and help booth from russia and SAA (normally you will not see anything of that on your west propaganda, or very short news) if the roads are open. But when rebels invade a city and stop anything from entering and start stealing food and similar for their forces, you will see this happening, or when simply the fighting is going on and nothing can enter or exit. Rebels should stop using civilians as their human shield, but they normally will not do that.
Now to talk more real Russian is helping in direct arment of SAA troops, training, air raids on terrorist groups, supply routes and similar. They do also a lot of the same shit as USA does, so there is no excuses there, but one important thing is unlike USA, that invaded other countries, russia went to defend a counter from foreign backed invasion. A core difference. Not saying russia are great, or SAA are great, I mean they did a lot of shit, use imprecise and old weapons that do kill a lot of civilians and similar. But you fight with what you have.
Yeah, the rebels are able to continue fighting and push the SAA back and still have even tanks left, that should tell something about how effective the Russian intervention has been... Or at least about how weak the SAA actually is.
No, the thing that shows is how good outside support the rebels have, and how fanatic fighters they have when they run with their suicide bombers. And the thing that shows how good the russia intervention has been so far, is the fact that from the start of direct russian air support the SAA stopped losing the territory and started advancing. So that fact shows the russian are doing a good job so far, even with the limited air power they have in syria.
