The episode opens with 'You Should Be Dancing' and it's good. Harry Shum Jr and Heather Morris demonstrate their amazing dance abilities, perfect for the Saturday Night Fever theme. Meanwhile, Darren Criss leads on vocals and manages to execute the dance moves to the standard of his renowned dancing co-stars. The air split will be a treat for Blaine fans.
However, the number feels awkwardly placed because we have yet to see the glee club be assigned their task for the week. Blaine finally clears this up and reveals that Nationals is about 'vintage' this year. Will (Matthew Morrison) is on a mission to prove to the kids that disco doesn't suck, but I was a little disconcerted that he has wooden mannequins with everyone's faces on. That isn't weird at all...
With a voiceover into Mr Schuester's mind, we find out that he wants to help Mercedes, Santana and Finn decide their futures using Saturday Night Fever as the album to find themselves.
This focus relegates so many of the characters to the sidelines. Quinn and Artie, who dominated last week's episode, hardly appeared, while Sugar and Rory were mysteriously not in class. It's these little details that are letting down the season.
One of the major talking points is the introduction of Glee Project runner-up Alex Newell as Wade, a member of Vocal Adrenaline who wants to perform at Regionals as a girl. Mercedes and Kurt's reactions say it all - Newell's character was very in-your-face.
With Vocal Adrenaline back, that only means one thing: Jesse St James. Jonathan Groff returns as the new coach and is meaner than ever.
Kurt and Mercedes tell Wade not to dress up as his alter ego 'Unique' before Sue says his performance as a woman will knock Adrenaline out of the competition, making it easier for New Directions to win. If only it were that simple, Sue, as Wade wows the crowd (Newell looks surprisingly good in a dress and heels) and Adrenaline are through.
Back at McKinley High, Mr Schuester assigns Mercedes, Santana and Finn with the task of singing a song from the Saturday Night Fever soundtrack. Amber Riley takes the stage with 'Disco Inferno' but then gives everyone a reality check, despite Will's protesting. She tells him: "I'm cream in here, Mr Schu, but what if out there I'm just skimmed milk?"
Little does she know that former flame Sam (Chord Overstreet) had filmed the whole song on his phone. Two guesses where that's going. In one of the sweetest scenes of the show, Sam reveals his belief before leaning in for a kiss. Team Samcedes is back.
Elsewhere, Santana (Naya Rivera) thinks she knows what she wants - fame in whatever form - until Brittany releases a sex tape of them. However, Sue with Brittany's help gets Santana a full cheerleading scholarship.
Now how do you solve a problem like Finn Hudson? He's not talking to Rachel (Lea Michele) initially, and he throws the prospectuses that Will and Emma eagerly gave him in the bin. But Finn and Rachel make up - in fact, Rachel shockingly considers giving up her dreams for the man she loves before singing to him 'How Deep Is Your Love'.
Will gives Finn a talking to and sits him down to watch Saturday Night Fever, which resolves everything. Finn decides that he wants to be an actor and will move to New York with Rachel to pursue his dreams.
The three dreamers lead everyone in 'Staying Alive' with homages to the movie and white suits.
Overall, though, I was very disappointed. Ryan Murphy gave disco a shot but in the process threw every main storyline out of the window to fit in the songs. The fact that some characters were missing will be frustrating for fans, and stars like Harry Shum Jr and Jenna Ushkowitz were criminally underused. It's not the best episode but at least it gave a small insight into the characters' fears as they approach graduation.
- With this year's Nationals theme revealed as vintage, what song choice does that mean for New Direction?
- Quinn's odd pregnancy bump returns - Sue's baby bump seemed to differ in size each scene.
- Becky must be a speedy worker to produce all those white suits for the final scene.
- "You've been out of ideas since Madonna week."
- "R.I.P. Whitney."
- "He called me spoilt and self-centred. He can come and talk to me first!" Ironic, Rachel?
- I'm not sure about Cory Monteith singing falsetto. I don't think it comes as easy to him as it does to Chris Colfer but good try.
