Not all movies have to be intense and hard to figure out. Sometimes they can just be fun, and this one is.
You have to suspend disbelief on a few technical scientific things, such as sending a message from SETI into outer space, remember that radio waves travel at the speed of light, and the nearest star to use is 4.3 light years away. So at BEST it would take 8 years to send/receive a message, but most stars in our galaxy are 50,000 light years away or so, so the message to one of those would take 100,000 years to send/receive.
Then we can't create DNA of a human, how are we going to create the DNA of an Alien species from scratch given just the data about it? But don't worry about those details, just have fun with it, watch the pretty little half-alien girl kill with much gore.. And the team of experts they send to catch the now fully-grown woman/alien is kind of fun too. Very cliché characters, but still fun.
I like the deep, hard-to-understand movies as well, but this one kept me entertained all the way through. Not the greatest movie ever made but not boring either. A fun B-movie type science fiction/horror movie, but with good actors.
I'm giving it an 8, which to me means, "liked it", whereas a 6 to me would mean "it was OK". It was more than OK so I give it an 8.
