With the big holiday releases pouring in, studios are taking advantage of attention towards such films as Harry Potter, Narnia, and Tron by delivering some sneak previews of film's to come. Which trailer's tease well, and which are more likely to scare away?

Green Lantern
--------------------------------------------------------



One of the most beloved super heroes of all time, DC's Green Lantern is long over due for a screen adaptation. Starring hear throb Ryan Reynolds as the title character, the film seemed sure to deliver. That is until this overly sexed up, unconvincing, and downright silly trailer started airing in theaters starting last November. Fans should keep their fingers crossed that this film stays their brightest day, and not the blackest night it seems to be.

Score: D+

Cowboys and Aliens
--------------------------------------------------



This gritty and violent trailer makes its point very early on: Cowboys and Aliens is not the fun comedy rump people were expecting. Not even playing to its camp value at all this haunting and effective teaser creates a sci-fi western that is cool, realistic, and creepy. Add in some badassery from Daniel Craig in the lead role and you have a killer trailer for a film that's quickly becoming one of the most anticipated releases of next summer.

Score: A

Transformers: Dark of the Moon
-----------------------------------------------



An announcement trailer, as Michael Bay put it, this teaser for next summer's Transformers sequel, and probable finale, surprisingly works. Although hinting at a conspiracy that may well be the film's down fall, there is little denying that this tease is as intriguing as it is visually stunning. Here's hoping to a sequel that delivers on its potential.

Score: B+


Thor
-------------------------------------------



A gamble to begin with, Marvel's Thor adaptation still stands on uneven ground. Although sporting some impressive visual effects, a strong cast, and a increasingly interwoven multiverse (note the SHIELD agent from Iron Man), there are things about Thor that just seem off. Asgard looks more like a Flash Gordon sequel then a home to Norse gods, and many of the costume designs are incredibly goofy. However, the Earth scenes fairs much better, with Natalie Portman and the famous Destroyer armor stealing the show.

Score: B

Pirates of the Caribbean: On Stranger Tides
--------------------------------------------


Although not the train wreck many were expecting, the first glimpse at the fourth Pirates of the Caribbean film is still worrisome. Most of this comes from the film's apparent overreliance upon Jack Sparrow to carry the film. While the drunken pirate was easily a high point of the previous three installments, being tempered with a strong supporting cast, now absent from the series, kept the audiences from feeling over exposed. Jack's antics even grow tiring within the course of this trailer, with little else truly going on. Even more concerning is the injection of a love interest that does not seem to fit the feel of the series or the character. Fairly, there are moments of genuine fun and it is good to hear those old music cues agin.

Score: C+
