Nah, dude. You've nailed a lot of it. Unfortunately, a lot of modern movies end up in two categories:
Trying way too hard to be cheesy for cheeses sake
or
Trying way too hard to be spooky/serious and ending up being bad cheese instead of good cheese.
The CGI and Star Power infection has a lot to do with the mediocre crop of movies that have been pushed out in the last 5 years or so. The great thing about the old days were, you had to imply it or risk a ridiculous looking bit of FX to get it on the screen. The great thing was, it worked most of the time either way. Now that CGI has become the standard, any movie with a budget can throw whatever the hell they want on the screen and most people will buy it. Plague of locusts? Why not?! We have CGI!
What this all boils down to, for me, is that the movie makers of the 80's seemed to have a lot more fun with a lot less to work with than modern movie makers do. It reflects in their work and reflects on the viewer. Not saying I don't appreciate a good modern special FX extravaganza, but most of the heart and soul is gone and reprehensibly replaced by dollar signs and big name value.
