No spoilers (I think) !
I admit it - I am a Gleek, have been since I discovered it on a transatlantic flight on BA back when they showed the Pilot episode.
The first three seasons were wonderful, but the beginning of Season 4, where the major changes to the locations and introduction of new characters was a little slow, but stick in there ... it gets to be a whole let better, and on second, third ... and tenth viewing, the first episodes of Series 4 grow on you too !
Major changes to a much loved series can alienate fans, and take some time to grow to be loved, but I can honestly say that I am beginning to love them almost as much as the previous New Directions team members, but of course, most of the old favourites make at least some appearances throughout the series. Those guys must have seriously deep pockets for all the airfares getting back to Lima so often !
Unusual move to turn the fourth year in the story into a two series (Series 4 and the current Series 5) structure ... didn't see that coming! Of course, our heroes get a plot line twist that boosts them when we think all is lost ... it wouldn't be Glee if the dreams didn't come true!
There are some serious issues covered in episodes of this series, and not everything is resolved before heading off into Series 5, but the music is great, the acting is delightful, and I am eagerly anticipating the twists and turns that will come out of Corey M's sad demise, and the resolution of the still open plot lines.
