This particular episode of Smallville is probably the best episode to air since reunion. This is for many reasons. For example, it takes the series back to some of it's roots. It welcomes back Lionel from a supposedly long absence, with the Luthorcorp plaza office in Metropolis. This room hasn't been in smallville for a very long time, and seeing it again brings back many memories from the smallville's past. Not to mention, Lionels conversations with Lex are always admirable.
Another pleasant return is, well uv guessed it, is Bart Allen(aka Impulse), AC(aka Aquaman) and Victor Stone(aka Cyborg). Not only does Steven Deknight reunite the former justice leaguers, he blends them in with the Smallville formula in such a unique way, that it almost feels like it is a feature length movie.
From there you get the basic story, Green Arrow forms the league, attempts to blow up 33.1, Bart gets captured, Clark saves him, and the facility is blown to kingdom com. All is good and graceful, with a good mix of stealth, action, pace and suspense. Oh, and Cyborg has some cool new upgrades true to the justice league character :).
The music is probably what makes this episode work so well. If you remember correctly, the first episode Steven Deknight directed was Agless from Season 4. This was a mediocre episode, but something felt out of place. maybe it was the music, or the acting, or the fact clark sais at the end "we didn't find you, you found us", kind of made people lose faith in the formula. But thankfully Steve Deknight redeemed himself in this Justice episode.
I had a few quivvles about Justice that made it fall short of the full 10. First of all, the far too cheesy exit of the justice league from the Ridge facility expolsion. I mean it would have been soo much cooler if say Green Arrow and Cyborg took off on Oliver's bike (rememeber from the arrow episode). Clark and Impulse should have obviously ran, and aquaman should have swam via another route. But that was soo incredibly cheesy, it nocked off 2 points from the full 10.
Secondly, another cheesy moment, not as bad as the first, but when Green Arrow sais "let's go save the world". That made me cringe. All in all, judging by the acting performances, music, direction and production values, the pros do outweigh the cons, and this is still one of the best episodes in smallville history, and maybe the 2nd best episode in season 6.
7 Out of 10...

A young man kills a young woman for no reason. The man's brother is jailed on charges that he was an accomplice, but soon escapes. Upon escaping, the seemingly innocent man kidnaps three victims and soon he ropes his girlfriend in on the plot. If this isn't bad enough, the situation quickly makes a downward spiral.
This film had some good aspects and many bad ones. Its strongest aspect was lead actress Emily Haack. Setting aside the fact she's nude in a fair amount of this film, she presents herself as a decent actress and a very strong character. I see no reason she cannot take this experience and somehow turn it into a career in some way. I was convinced she was a ruthless individual.
Also, the makers of this film were very bold and pulled no punches. Graphic nudity (both male and female), coprophagia, and extreme anal violence are not shied away from. I like my horror films to push the boundaries a little bit, and this one ignored them altogether, gladly skipping towards Gomorrah. Maybe it was too much, but I think they achieved what they were looking for.
But now the negative aspects. First, and most noticeable, this film is very low budget and the film quality shows this. I can excuse that -- the plot was decent, the acting fine and in some scenes the lower quality film actually made the movie more disturbing (a more realistic feel). So, I won't scold them for having low-grade equipment. What I will scold them for is the use of poor choices in shots. For no reason I can ascertain (besides plumping the movie), there is a large amount of footage of a cemetery. I don't really know why, and I frankly started dozing off at this point because it was so long and pointless.
I also take issue with the title. The idea here was to deceive people into thinking this film had some connection to the classic "I Spit on Your Grave". Now, there is a line that seems to imply the main character is the daughter of the woman from this other film. And the themes are very loosely the same (a woman getting revenge on men). But there is no firm connection and the reason this title was chosen was for the video store customer to think they were getting a sequel. This was deceptive and dishonest.
My last major complaint is that this plot makes no real sense. Not even a little bit. A woman is killed in the beginning for no reason. A prison escapee finds time to kidnap people to torture them, for no reason (because they wronged his girlfriend?). The same man goes from good to very evil without explanation. Likewise, the female lead (Haack) turns fro ma normal person to someone who is overly cruel and sadistic, for no reason at all, and against people who for the most part were only marginally mean to her (a neighbor offering drugs for sex is wrong, but by no means worth getting tortured for).
Don't let this title fool you, or the claims that the film is incredibly shocking. Yes, some scenes were shocking, but the vast majority of the film is dull and makes you want to take a nap. If you see this in the video store or on Netflix, just keep browsing. Or rent it, and we can sit around and vent about it for hours. You have been warned.
