I believe the author is saying that "The Godfather" was able to capture the subtlety of communication between Sicilians. Meaning how most Sicilians communicated with each other during the time period. The author is saying, "in particular" to show that he's impressed with the way the movie recognized this subtlety of communication among that group especially. In the second part of the sentence, the author is saying that "The Godfather" also captures the essence of how Italian people in general communicated with each other. In other words, how the majority of Italians communicated with one another.

"Why are you making a face like that?" "Why are you looking at me like that?" "Are you mad at me?" These are the correct way to ask all three. "Why are you looking at me like that?" and "Are you mad at me?" are both very natural expressions heard all the time in English.

Watching TV could be harmful to children. Watching is a gerund. 1) Wasting time is a great problem of modern times. (Why couldn’t I replace 'waste' with 'wasting'?) You already have wasting in the sentence. 2) This step prevents wasting time 3) Just wasting time and money. Incomplete sentence. You would have to say something like, “Just wasting time and money is bad.” If you wanted to stop at money you would have to say, “It’s just a waste of time and money.” 4) GIS and MCDA were developed to minimize the wasting of space in hazardous waste landfills. 5) You have to pay for it and you have to pay for it with your life, spending a lot of time, you pay for it with time, not the wasting of time but the spending of time. 5 is not grammatically correct, nor did it sound natural. 6) She liked receiving his call every evening. (his call) The last five examples were found on a linguistic search engine and are supposed to be perfect, but some people say that 'wasting of time' isn't correct. Why can’t I use 'a wasting' instead of 'a waste'? ‘a wasting’ does not make sense grammatically. “Slow internet speed is a wasting time” <incorrect “Slow internet speed is wasting time” <correct “Slow internet speed is a waste of time” <correct Same with the examples below. “I’m a swimming” <incorrect. “I’m swimming” <correct. “I’m a telling him” <incorrect “I’m telling him” <correct “It’s a Thanksgiving” <incorrect “It’s Thanksgiving” <correct A lot of verbs are used like that. Swimming Telling Watching Talking Calling Thanksgiving is also a gerund.

All are perfectly fine to say. I would probably change 'come' to 'be' in the 3rd statement, but it's fine the way you have it.

Meditation, exercise, a clean diet, no caffeine after 2pm

No. By itself, it should be "What gives you confidence?" to make a general question. To use 'the' in the statement you must follow it up with what 'the' is referring to. For example, "What gives you the confidence to play basketball at such a high level?".
