Okay so just to give you an idea of what we're talking about here. Let me explain a scene from the very first show.
So their spaceship is basically a suburban McMansion and they even have an all-terrain vehicle with big knobby tires in their 'garage', just like mom and dads SUV back home. At one point, the family's seen barrelling across rough terrain being chased by a dangerous storm, dad at the wheel, mom turned around in the passenger seat, making sure her cherished offspring are all okay in the back while one of the daughters (the 'rebellious' one), rips open a bag of Oreo cookies and starts passing it around the car! I kid you not - this shameless product placement - REALLY does happen! LOL, It's all so insanely ridiculous.
At another point, the momma bear is cleaning out a rocket engine and treats it like she's just cleaning furnace ducts back in the burbs. She also has a big 'white board' she uses a marker on and makes big 'to do' lists for every one to follow, just like the one on her fridge back on earth no doubt. And don't worry - Dad does similar cringe-worthy suburban cliche 'dad' things as well.
So there you have it... you've been warned.
