On the whole, Season 2 of the hit US television show (well... phenomenon, let's be honest) is a very enjoyable affair. The season features some awesome storylines, some great song choices (and performances) and the acting this season has been outstanding; and a vast improvement on some of Season 1's more wooden performances.
The show develops into a more dramatic affair this season; if I were to sum up the seasons themes in two words I would use "ambition" and "acceptance" - Rachel struggles through the season juggling love with her ambition, whilst Will just struggles with love during these 22 episodes; meanwhile, Kurt fights to be accepted by his peers and Artie begins dating one of the most popular girls in school whilst Tina and Mike begin an Asian fusion of romance.
The season also introduces some great additional characters; Sam and Sunshine are fantastic and cute additions to the show and both have truly outstanding voices, Blaine - the lead vocalist to a rival show choir - is truly brilliant and completely lovely, whilst substitute teacher Holly Holiday is hilarious (although she slightly outstays her welcome). Meanwhile, some of season one's supporting characters have moved up to season regulars- Brittany and Santana have been excellent this seasons- Brittany's one-liners and Santana's fierce attitude and catty comebacks literally add some of the best comedy into this season (aside from Sue, obviously!).
Unfortunately Season 2 of Glee is a relatively confusing mash-up of very enjoyable musical television comedy and poorly planned plots lines. On the whole, the season is great fun to watch, as was season one, and should you be a standard fan of the show, it does itself justice. Meanwhile, if you a very massive Gleek like me, the flaws and inconsistencies become a little tiring and frustrating- sometimes its like they're making it up as they go along; and given the shows enormous success, it's pretty much inexcusable.
But on a show-by-show basis; there really are some great episodes - "Britney/Brittany" doesn't quite meet the Madonna-episode standards but is brilliantly executed and Heather Morris does an outstanding job playing Brittany in this episode, "Born This Way" is this season's GaGa episode which is really enjoyable, "Prom Queen" is a highly intense and truly wonderful episode whilst "Funeral" is brilliantly moving and darkly funny too.
However the best episode, in my opinion, would be "Duets" which really takes on a full ensemble approach and we get to enjoy every character equally- look out for the Santana/Mercedes performance of `River Deep, Mountain High' which is brilliant and Kurt's performance of `Le Jazz Hot' which is sensational. Also, the season finale is pretty much amazing- although a little flawed (sadly) but there are some utterly breathtaking moments!
On the whole, the season is really enjoyable and I do recommend it as an avid viewer. To those, who like me, are just a little bit addicted- well it's not all bad; we can just hope that the writing team pick up their game a bit next season to produce a show with some consistency to its storylines!
