It all comes down to size.. they've made some nice additions into the gave since release but there's still one big problem, Size of the maps. They released DLC not long ago and basically tried to cram more people into a city by offering massive futuristic skyscrapers. I haven't seen the reviews but I'm pretty sure it flopped. Also everytime they released a patch they claimed they had fixed the money sharing issues. well after 7-8 patches the issue is still there. The Maxis dev said on reddit that size was due to hardware limitation but most people aren't buying that. When and if they do release bigger maps and possibly some type of world edit then the game might be enjoyable like it used to be with Simcity 4.
