You can still tell what they are, the species is not mistake, BUT I really loved some of the things about the original that have been changed.
The original did not have giant hands or feet. The fingers had a lot of biomechanical details even.
The guy in the suit was 6'9", some sources say 7'1. Either way, he was very tall and skinny.
That really helped the look, and those little details really made the Alien come alive.
Today they seem to have lost that quality.
