Old Effects That DON'T hold up.

[Doggett]

The end fight scene in Robocop 2 looks really weak. !

In Lou Ferrigno's HERCULES the chariot ride across the stars looks like just what it is: a Hercules action figure glued to a toy chariot.

The Terminator eye surgery is pretty bad, but even worse for me is the high-tech disguise from Total Recall. The mask comes off to reveal what briefly looks like a wax sculpture of Jean Claude Van Damme.

There's also the matter of building the effect without considering that it needs to look like there's room for a head in there. What's with that huge ear/piston thing that pops out? Where's Arnold's head supposed to be in relation to that?

Total Recall good God yes! I love that movie but those special effects are awful.  The one above is a prime example but don't forget the scene where "Arnold" sucks that bug out of his head through his nose.  Then theres the eyeball popping out scene outside on Mars.  Yikes!

Mortal Kombat CGI is honestly one of the worst ever.  I recall watching it thinking it was cool back in the day.  Watching it now is painfull.

Any late 80's-about mid-90's movie that used CGI (and that wasn't a CGI animation movie like "Toy Story.") Sure, it was mind-blowing then to see actors interacting with things that had previously only been rendered using jerky stop-motion animation (I still love that particular technique, but it really does look better when the whole movie is stop-motion), but now...I dare you to watch that one scene from "Poltergeist" where all the toys are flying around in the boy's bedroom and NOT laugh a little.

Reptile in Mortal Kombat (1995) isn't the best ! haha

I watched the original Terminator recently and remarked on how bad the stop-motion climax scene looked.

It's been a while, but I don't believe any effects work in Poltergeist is CG.  It did come out in 1982 after all.  I also can't recall any effects work that isn't excellent - what's wrong with the toy flying scene?  They don't quite match the way they should in the background I guess..  I couldn't find the whole scene though and I don't own the film.

I'll agree with the sentiment though.  I thought many of the early CG films looked bad even when they were new.  Another one that sticks out is the cow flying in the air in Twister.  It's old as far as the world of CGI is concerned at least.

No it doesn't! 
It's probably the best and greatest stop-motion fight of the modern era, it blended live-action and models together almost flawlessly!

It's not CGI, it was done on an optical printer. I think it looks quiet good, you can tell alot of work went into it because you can barely see the matte lines.

Any dinosaur/giant monster movie that involves hand puppets for closeups.

Godzilla Raids Again from 1955, the sequel to the very first film. There's a scene where you can easily see that two hand puppets on a stick were being used for the fight between Godzilla and Anguirus.  A thing tha would be reapeated in 1962 for King Kong VS. Godzilla in one scene.

Any movie where lightning is drawn on.  I crack up when I see it.

I love that scene.  So you got rapidly decompressed, all your veins and capillaries burst, your eyes pop out of your head.  But then when pressure is restored, all your veins and capillaries and eyeballs magically heal in 2 seconds and your eyes suck back into your head.  Tee hee.

The Special Effects in Star Trek 5 are pretty weak.
Paramount decided not to go with ILM for some reason...
Heck what am I saying. The whole movie was pretty weak!
