For this "Glee" episode, the showcase is on Artie and Tina concerning Artie's impossible dreams, Jesse helping Rachel finding her mother, and Will encountering an old friend named Bryan Ryan (Neil Patrick Harris). I'll stop there and just say what another entertaining episode this was what with Kevin McHale giving his wheelchair-bound character a wonderful dream of being able to stand on two feet and doing "The Safety Dance" at a mall with others, seeing Matthew Morrison and Harris dueting on both "Piano Man" and "Dream On" and Lea Michele and guest star Idina Menzel on "I Dreamed a Dream". Tina and Artie make a fine romantic team here and seeing Rachel having mixed emotions about her new discovery is another fine dramatic moment for Ms. Michele. Kudos to director Joss Whedon which shouldn't be a surprise to anyone who's seen his "Buffy" musical episode-"Once More with Feeling". Can't wait to see the next episode of "Glee"...
