10/10? Meaning this is the best there *can possibly be*? On basis of what? Make no mistake, this is a great episode, but it's far from *perfect*. Too many IMDb users write reviews from *highly* subjective viewpoint, and while they are useful in telling the average reader, what the reviewer likes, they could be more than plot summaries (there is a different update section for that) topped of with a few gushing praises.
So, in a nutshell: great plot and character development, good acting, laughs and drama, *but* Glee's main problem remains: the playback/attempts at lip sync performances are so out of sync it's *distracting*. The singers clearly are talented - why isn't there anyone on the production side making sure the vocals match the lip movements? If bands can put out live recordings with 100% audio/video sync, why can't Glee do it? Until then, we get just a shadow of Glee's full potential, "only" 8/10 at best - like this episode.
