Megan's world is turned upside down when she hears her calm life with her little brother and single mum is about to change. She hears she's soon to have a stepfather and a stepsister. Megan thinks they're a bit weird and is determined to stop the wedding. She discovers they're actually even stranger than she thought - they're from another planet.
Bad watch, probably won't watch again, and can't recommend.
This is one of the movies that came out of the low budget studios that Disney owns and will stamp "Disney" on, but clearly aren't part of "Disney Studios" or the Disney budget.
That wouldn't matter as much if the writing or acting was really good. Courtnee Draper was a decent actress in this, and poor Tamara Hope had such a horribly awkward character that I can't tell if she was the best actress playing a bad character or the worst actress. Most of the rest of the character land around this level.
While "The Secret World of Alex Mack" proved otherwise, this movie really makes me feel like we do not need to mix high school social drama with alien invasion, ever.
There are just so many other things to watch out there, don't waste time on this one.
