Intelligent people judge a game based on it's quality, not based on how many mindless lemmings who got told by a friend of a friend of a friend to buy it jumped on board for a month, or two, or three.
Swtor is definitely not a horrible game, but it's missing alot of very BASIC features which have become a standard in the mmo community as quality of life improvements, also there's very few ways to play through the game as far as avenues of leveling go, you pretty much have to play through all the same crap and break your spacebar doing so for any characters past the first on all but the class story missions.
pvp isn't a viable alternative way to level
space combat isn't a viable alternative way to level (since they nerfed the **** out of its xp yields in beta outside of daily quests).
