Glee S6 - Teaser Review

A few hours ago, Glee just released their promo/teaser for their final season, number 6.
And It's just what we're asking for!

So our adorable Rachel (Lea Michele) and Kurt (Chris Colfer) are back! <3
And it looks like it's all about bringing back the a Cappella club back, and it also looks like they're gonna be butting heads with Ms Sue - like always-, who said "You will beg for death" ...

                                         
Also later in the teaser, Rachel and the guys are singing the one and only "Let it go" !, and she looks stunning!
                            

The last few seasons of Glee had always made me wonder about the writing, the cast is like super talented, but the writing is really poor and getting more and more cheesy, I hope the final chapter gets wrapped up well this time!

By the way, where's Idina Menzel? She doesn't show in the teaser at all?!!
