Snippet: "Last summer gave us the DC bomb that was Jonah Hex and this summer offers the colossal disappointment that is Green Lantern. The epitome of spectacle over substance, Green Lantern is a cosmic mess and a huge letdown given the source material it had to draw from. Indeed, X-Men: The Last Stand and Wolverine are better than Green Lantern. This was DC and Warner Bros.' best bet yet at establishing a deeper bullpen of big screen superheroes beyond Batman and Superman, but the film is bad enough to possibly kill any hope for ever seeing The Flash or Justice League."

"Remember when big, summer blockbusters were fun? That notion apparently eluded the makers of "Green Lantern," a joyless amalgamation of expository dialogue and special effects that aren't especially special."

"Still, Hal must undergo the obligatory training montage to learn how to harness his new-found power. The ring allows him to create whatever he can envision in his mind, which would theoretically provide a great opportunity to inject some imagination into this otherwise dull film. But the stuff Hal constructs is pretty lame, which only highlights how idiotic the mythology of "Green Lantern" truly is."

"Now let's cut to the chase: The movie pretty bad. Yup, you read it right it was just BAD (I hate saying this but the critics were right). The movie just didn't live up to its expectations. So i'll try to make this as simple as possible."

"It's a state of the art superhero film if the year were 1995. If this were released in the same summer as "Judge Dredd" and "Johnny Mnemonic," this would look pretty solid by comparison. "

While DC Comics are constantly proving themselves ahead of the curve in the comic publishing business, "Green Lantern" shows they have a long way to go to catch up with Marvel in terms of bringing their characters to the screen in a way that can please both fan and novice alike. There's little about "Green Lantern" that will convince non-comic readers to care enough about the characters to want to see more of them even with an obvious after-credits scene that just adds insult to injury, not just because it should have been dealt with in the body of the movie but also because by then, we just don't care to see what happens next.
