Glitzy ‘Glee’ delivers on all levels

To consider viewing anything “Glee”-related, much less a big-screen 3-D extravaganza, you must accept – no, embrace – the undeniable cheese.

“Glee: The 3D Concert Movie” is exactly what it purports to be: a live concert filmed in 3-D, so that familiar Slushee-in-the-face (the punishment bullies impose on glee-club members almost daily) is more startling than ever.

Add streamers, fireworks, fog and misunderstood diva Rachel Berry’s face to the objects jumping off the screen, and you get the feeling that you’re actually there, with the best seat in the house.

For “Glee” lovers – even those who already attended the live concert – the movie is a must-see. Backstage documentary-like moments where actors are casually in character feed our admittedly irrational but unending desire to believe they’re real people.

Between the embellished musical numbers, where “Glee” favorites Rachel (Lea Michele), Finn Hudson (Cory Monteith), Kurt Hummel (Chris Colfer) and the lot perform show tunes and pop songs from the hit show’s two seasons, filmmakers fortify the bubblegum by spotlighting three concert-goers who were particularly inspired by “Glee.”

One is Janae, who despite being a dwarf joins her high-school cheerleading team – the coach, very unlike Sue Sylvester, admits she’s their secret weapon because her size makes her a flier – and then earns the title “prom princess.”

Trenton is a gay teenager who was bullied and forced to change schools when he was outed in eighth grade. And Josey suffers from Asperger syndrome, a form of autism that causes extreme social anxiety.

They describe how watching “Glee” showed them that they’re not the only ones who are different, that being the underdog should be celebrated, that they want to inspire others.

Cheese, cheese, cheese. And we eat it up.
