Why do they make David and Mary Margaret so corny?

I hate to say this considering how much i Cinta the tunjuk but for the longest time, i don't always like how the the tunjuk portrays MM and David. I mean for one, they really overdo it with all the Ciuman and hugging each other and sweet talk. Also and this is lebih 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 lebih 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 lebih badass which is why I always Cinta 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 lebih often. In my opinion, that really expresses a real-life and healthy couple. Again I don't want to offend and again, I Cinta the tunjuk and I do Cinta Snow and David (most of the time). I just sometimes wish they could've been portrayed a little differently.
