What do people think about Lang's textbooks? I am learning Complex Analysis for the first time from Lang. (literally the 1st time I'm seeing ANY sort of complex analysis/calculus, although I have extensive experience with real analysis). I have gone through quite a love-hate relationship with this book. At first, I hated it with a PASSION, namely because it seemed a little too "wink-wink" look-how-clever-this-mathematics-is feel without being too systematic, formal, or elegant. But then I fell in love with Lang's decision to systematically cover formal power series from an algebraic point-of-view before ever considering convergence. But then I also still hate the book because it seems to bury really important techniques/results in "examples". (Even a simple remark, like "the above is important." would help.) For those with more experience with Lang's numerous textbooks, what do you think? Lang's textbooks seem to have a specific flavor that is antithetical to the flavor of, say, Royden/Fitzpatrick or Munkres. Some have criticized Lang for churning out too many textbooks, without much care. Just interested in what people think about Lang. P.S. Also, any good companion textbooks for Lang's Complex Analysis?
