When I was a kid, I saw an old 50s movie on TV that was abut an alien invasion. The main characters awoke to an empty city, no people but plenty of killr alien robot invaders. They finally holed up in an apartment building for most of the movie with the aliens tryng to get in until the army came by with a means of killing said aliens; turns out these people had missed the evacuation call. Why do I mention this? In Skyline, a bunch of people wake up to an alien invasion, the city nearly deserted (the aliens took them all), and they spend most of the movie holed up in an apartmen building with the aliens trying to get in until the army arrives to fight the aliens (and get stepped on by said aliens). The other difference? The 50s movie had cheap special effects, even for the time; Skyline had cheap special effects for our time (great aliens and ships, but being set in LA all they needed was stock footage). The 50s movie had a bare-bones plot; Skyline was missing an ending, needed about another half hour at the end, and could have used some logic at the end. The 50s film was designed and written on the cheap, with low production quality; Skyline looked like a movie of the week for ABC.

So, I guess what I'm saying, is that I liked that old piece of 50s schlock better.
