this movie is bit different than the previous installments.this time Mercenary Carl Thomasson(Treat Williams) poses as a teacher in an elite military school.the reason,a friend Who also happens to be a general at the school,has asked Karl to help him eradicate the white supremacist element which has infiltrated the school.i didn't like this movie as much as i liked the previous 2 in the series.i did however,think it was better than the 1st one.there is lots of action in this 1,just like the last 2,so that can't be the problem.i think there may be 3 reasons why i didn't like this movie.the 1st reason is the setting.although the general plot of the movie differs very little from 2 and 3,i think i just prefer these movie take place in a high school or university setting,not a military academy.i also didn't find the white supremacist angle very interesting.i think the filmmakers tried to add another dimension with that angle,but i think it was a bit too much for this kind of film,a bit too complex an issue.i prefer the simplicity of the 1st 2.the other reason may be the fact that i am getting tired of the series and losing interest.whatever the reasons,this 1 is not quite up to par with the 1st two.i'd have to give "The Substitute 4" 6.5/10

Treat Willaims returns as Karl Thomasson who once again this time teaches at a military academy where white supremacists are ruling with an iron fist (Led by Patrick Kilpatrick) here Williams uses his marine issue training to take on kids who also have the necessary hand to hand goods to give him a run for the money. Also there is Bill Nunn and Angie Everhart who provide our hero with the goods necessary (That is sex in Everhart's case) to squash their movement right here, right now. I just noticed that this entry was directed by the guy who gave us Best Of The Best and it's even dumber sequel. I was going to compare this to Best Of The Best 3 which is among the most offensive movies ever made but in doing so the fact remains that Radler isn't guilty of making such lousiness. The Substitute 4 is actually not too bad in it's B.movie type of way, the movie has tons of violence and Treat Williams holds his own surprisingly well and the racism angle never feels offensive since we aren't treated to a pretentious attitude regarding it. Therefore the movie is watchable and works in satisfying the type of person who rents movies that bypass theaters. In this regard the movie works and it has some quite exciting action in the process. The only problem is that, well it also inherits the problems of being a B.movie and therefore it is predictable, unsurprising and silly. In other words your perfect guilty pleasure.* * out of 4-(Fair)

I dont get it. We have a very good movie, with a good sequel, a fair second sequel but Substitute 4: Failure Is Not An Option is just plain stupid. The only thing good in this movie is Treat Williams because he is an awesome actor and knows his role very well. Basically this storyline is just like any other action movie, white suprimicists taking over a military base or whatever and the hero comes in to whipe the whole mess free. Like I said, Treat Williams is the only thing in this movie that actually makes this movie worth watching. Well I guess I give this movie some credit since how the acting isn't so bad... five out of ten stars.

Okay, when I saw it in the video, I just couldn't believe it...after a first boring film, they made a second one, and after the very bad second one, they made an awful third one, and after the third one, here goes the forth one...Well, let's just say it is worse than the first and second ones, but better than the third. But it still sucks a lot. Some gratuitous nudity scenes, some cheap action sequences, and when I say SOME, it doesn't mean a lot...nothing happens during the whole movie, until the very predictable ending...One important point is the one liners...they are so awful it's terrible...the problem is that it is SOOOO evident that it's a mechanical and not natural sentence that comes out of Treat Williams' mouth...the acting isn't so bad, especially in William's case, but the way he says his one liners makes it a bad performance, and another factor to approve this fact is the stupid and pointless character that they offered him...and why is this called The Substitute??? The guy's just a mercenary, and he's in a military school, he's more a soldier than a teacher, he always beats up one student...with teachers like that, don't ask yourself why there are so many high school drop-outs...I mean, in the first and second films, the agent was a substitute, but in this one he isn't...There's an error in the script because they kill young boys in Panama, and one of them has the Werewolves' sign in his face (The Werewolves are a clan of nazi students at the Military College, and they are only 5 or 6 of them, so none of these folks could be in Panama...). This film has a very conventional script, with even less flavor, some below average acting, and boring directing. I guess we should wait for the fifth one, then the sixth one, and then the "Substitute Gift Box"...bad film. 4/10
