You know exactly what kind of movie you are getting when the movie poster is just Schwarzenegger holding a gun with his arms bare. You don't cast Schwarzenegger is acting is a priority; you hire him to flex his biceps and say corny one-liners. He delivers a standard Schwarzenegger performance; it sucks but he looks like a bad ass. Predator is full of explosions and gore. It's comedicaly unrealistic, but Predator is the dumb fun you want. The issue is that that is all there is. Predator has a plot as simple as go here, do this, go here to get home. There is nothing more. That would be fine if it did all of that well, but I think they spent all their effects budget on pyrotechnics, because the definitely skimped on the CGI. The Predator sees in heat vision (My brain isn't pulling out the right words here, he only sees body heat or whatever heat there is), he has a cloaking device his uses often, and her has glowing green blood. For 1987, I guess the cloaked effect is okay. There are a few times where you can tell that they didn't use a guy in a green suit and went full on CGI and it looks bad. The heat sensor vision doesn't seem to accurately represent what the actual body heat would be. The clearly didn't use a heat cam and just painted on an estimation of what some guy though it should be. The worst is his glowing blood. Had they just left it nuclear green, it wouldn't be so bad, but they fuzz up the edges to make it look like it's glowing. It looks like something out of Ghostwriter. There are also a few scenes (most notably where a character takes a tumble off a cliff into the water) where the video quality suffers a huge downgrade. Everything looks fine (for an 80's film) except for a handful of scenes where they either used a different camera or were zoomed in from far enough away that everything is blurry and pixelated. Predator is a loud, dumb, exciting 107 minutes of generic Schwarzenegger and blood and explosions.
