Absolutely.
I settled for a little NECA one today. It was the version in the Kenner repro box. When I took it out and looked at it, the dome was crooked, so, I peeled it off, and looked at it to see what I could do. Whoever trimmed the vinyl didn't do a good job! There's a nick in the front edge and they trimmed too much off one part of the back. I evened the sit a bit, touched up rough bits with Citadel Nuln Oil and glued it back on with some PVA. I then noticed that the 'hoses' going from the jaw to the back were too short which limited side to side movement of the head.
To start with, I was annoyed, it was the last one in the store, so I'm stuck with it. However, I stood it up, put it where I wanted it and stood back. There, in front of me was the Alien. The flaws seemed to disappear and I realised that what I had was everything I needed it to be. Sure, it isn't perfect, but, here's the thing...
IT WAS NEVER MEANT TO BE!!!
It's just as you said, it was meant to be glimpsed, kept in shadow to heighten our fear of what we couldn't see. Our imaginations made it look far scarier than it ever was. As I look up at it now, the Alien is there, and that's it, it's there and that is enough.
