It seems that there are a lot of complains. I won't count them all but ''Skyrim is not an RPG'' or ''The game forced me to become invincible with smithing'' are some of them.
I'm here to remind you that these are hundreds or eventually thousands of people complaining. But you forgot the fact that the few million others rather keep themselves busy with Skyrim, one of the best RPGs till date. Just a heads up.

Whoever says smithing makes you invincible is an idiot.
