Why do they make David and Mary Margaret so corny?

I hate to say this considering how much i 사랑 the show but for the longest time, i don't always like how the the show portrays MM and David. I mean for one, they really overdo it with all the 키싱 and hugging each other and sweet talk. Also and this is 더 많이 directed towards MM, she never seems to treat Emma as a friend anymore. I mean I know she's her daughter and stuff and it's cool and sweet if not a little creepy that she still attempts to treat Emma like her daughter but considering they're the same age, I think it'd be nice if MM could start treating Emma as 더 많이 then just her daughter. Kinda like how they're relationship was during the 1st season. At least David treats Emma like his fighting crime partner as well as his daughter. I don't know. I just always thought they would've had Snow be a little 더 많이 badass which is why I always 사랑 seeing her with a sword and crossbow. I hate to say it but in a way, I kinda liked the Snow White during "Heart of Darkness" when she was under the potion that made her mean LOL It's not that I want her to be evil, I just kinda wish that they could mix in some of that Snow from the "Heart of Darkness" scenes with the normal Snow. Another thing is that I kinda wish MM and David would fight 더 많이 often. In my opinion, that really expresses a real-life and healthy couple. Again I don't want to offend and again, I 사랑 the show and I do 사랑 Snow and David (most of the time). I just sometimes wish they could've been portrayed a little differently.
