Resorted to types, music cues, off the tear-glands

It's a pleasant surprise to see characters that are so well-fleshed out in a film that could've easily resorted to types to make its point. Yes, there are a couple of awkward dramatic scenes (like his meeting with the fundamentalists in the mosque or his efforts to rebuild a hurricane-hit village and his equally superhuman entourage of mediapersons and supporters who wade through flood waters) but it's all done with great earnestness and the right intentions.
Before you get an impression that it's all dead serious... No, no it's not. No, no. It's highly entertaining, it's as mainstream and popular as Hindi cinema gets with the romance, song and dance, sight-seeing tourist attractions, music cues that trigger off the tear-glands and Shah Rukh Khan quips that will make you laugh whole-heartedly. His chemistry with a fantastic Kajol (Tere Naina is so goddamned romantic) alone is worth the price of admission but this film gives you much, much more.

Could you please explain to me the emboldened parts?
