It's hard to hold back the smile that creeps onto your face once the New Directions gang takes the stage in 'Glee: The 3D Concert Movie.' Despite the constant spoilers, the "will they or won't they graduate?!" speculation, the uneven writing, the constant neglect of many main cast members, the nonstop parade of guest stars, and the misuse of Jane Lynch, at its core, 'Glee' is still fun.



Remember the feeling you got after watching the pilot? The misfits had a place, you guys! Music was inspiring! Jane Lynch was hilarious! Well, that feeling comes back (in 3D!) once the a cappella voices begin singing the opening guitar riff of Journey's 'Don't Stop Believing.' And when the movie spotlights real-live Gleeks affected by the show -- forget it -- you won't be able to leave without feeling uplifted.

Below, find three reasons why the movie gets us excited for what Season 3 of 'Glee' can be -- especially considering they've stocked the writers room with talented TV veterans who can presumably develop storylines throughout multiple episodes -- and two things that scare us (besides the unnecessary 3D).

You'll be seeing a lot more Darren Criss on 'Glee' this fall now that the actor has been made a series regular, and his first official duty as a full-time cast member is to hit up the crowded California chaos center known as San Diego Comic-Con.

The Warblers leader will head up the 'Glee' panel alongside fellow full-time newbie Harry Shum Jr. (also known as Mike Chang), Jenna Ushkowitz (Tina) and Dot Marie Jones (Coach Bieste). While Ryan Murphy will be M.I.A., TVLine reports that co-creators Brad Falchuk and Ian Brennan, executive producer Dante di Loreto and choreographer Zack Woodlee will be in attendance.

The panel, which will be held in Hall H on Sun., July 24 at 10AM, will be moderated by TVLine's Michael Ausiello and will also give fans a sneak peek at the 'Glee' 3-D concert movie.
