The Descent was not overrated. It is one of the best horror stories in recent years. They created characters with substance and ones you genuinely care about, and when they are put in this terrifying situation, you really feel bad for them. The confined setting, the suspense, pacing, direction were all well done. And yes, this does resemble Ripley going back in Aliens. I hope they made really great characters in this sequel and kept the feeling of the original in tact. I'm looking forward to it!
