When someone utters this very cliched line - "We're from two different worlds" - you know that love, moping and the furtive look of longing are seriously forbidden.
In Star-Crossed, a sci-fi version of Romeo And Juliet mixed with 90210, The O.C., Mean Girls and those cheesy sci-fi series where aliens come from outer space but still somehow look like very hot human beings - the two central lovebirds really do come from different worlds that are hostile towards each other.
The alien boy, Roman (90210's Matt Lanter), crash-lands on Earth as a young kid in 2014 from the planet, Atria (wherever that is), and meets a small girl in a backyard shed.
Fast-forward 10 years to 2024, Roman is bused to an intimidating high school in Louisiana amid tight security - read: America's civil rights desegregation of the 1960s - where he re-connects with that kind human girl, Emery Whitehill (Friday Night Lights' Aimee Teegarden).
She is the sort of solitary alien- friendly chick usually heroic in us- versus-them encounters like this.
He is not just the teen idol of his bunch but also the anointed leader of his race who preaches wise counsel.
"In case you haven't noticed, we're outnumbered by seven billion people," he cautions his best pal, Drake (Greg Finley), who is just itching for a brawl.
By the way, that 2024 set-up is something in name only, since nothing seems futuristic except for some low-rent weapons and alien-refugee uniforms which look like leftovers from Battlestar Galactica.
Now, you think we have integration problems?
These foreign folks are zoned off in a strictly guarded laissez-faire compound of crooks, gangs, thugs and dopers patrolled by armed human cops and slapped with curfews which make our ERP seem reasonable.
Seven of the alien teens are chosen to go to the local high school as an integration exercise and they stick out in the crowd, partly due to their Mike Tyson- style facial tattoos and mostly due to the penchant of the hotheads among the two separate groups to fight each other.
Oh, kids, alien or otherwise, they are all the same.
No, these aliens do not have special powers, except one girl can swim very fast, and using some kind of DIY blood transfusion, they have the ability to cure human illnesses such as cancer.
I tell you, if I know an alien who can do that, I would marry her.
Anyway, the whole point is to create - creator Meredith Averill worked previously on Life On Mars, Happy Town and The Good Wife - a testosterone-charged teen drama with aliens instead of the standard vampires, werewolves and whatnot.
