The much-awaited trailer of "Fifty Shades Darker" is finally out and it is getting a lot of rave reviews. The second installment of Christian Grey and Anastasia Steele's erotic love story looks quite a treat that the fans are hoping for. In fact, the "Fifty Shades Darker" trailer is a notch higher as it raises one's curiosity with many questions.

The "Fifty Shades Darker" trailer promises secrets, mystery and much more, but more importantly, it raises questions that have got fans guessing, reports E! News. The most important question comes to the fore with the opening moment of the trailer is, what is inside the box as it looks very ominous.

One also feels concerned about the mysterious masquerade and many are compelled to think as to what will happen at the masquerade ball. The same goes for another scene where Anastasia's photos are everywhere in the "Fifty Shades Darker" trailer.

Well, from the opening scene to the end, Dakota Johnson's Anastasia is omnipresent and fans cannot help but think why. The fact that she is followed is also enough to make fans feel concerned.

Another question that is hovering in the minds of fans is how Christian won back Anastasia's heart.  At the end of "Fifty Shades of Grey," we saw her rejecting the billionaire and moving away from his life. But the trailer suggests that the upcoming edition will have the couple back and the steamy scenes and rocking chemistry in the "Fifty Shades Darker" trailer suggests that the movie will take the heat a notch higher. The other women in Christian's life also serve to deepen the mystery as they seem dangerous as well as creepy.

In other news, it is being said that the second installment might not make as much money as the first edition. Forbes claims that the second and the third editions might not match up $571m collection worldwide. Well, how the film will fare in terms of collection, is yet to be seen but the superhot trailer does suggest that the fans will behold a lot of secrets unfolding.

"Fifty Shades Darker" hits theaters on Feb. 10, 2017, ahead of Valentine's Day.
