"Let Me Be Your Star" has received critical acclaim. AfterElton describes the pilot version of the song as "genius, blending an amazing cocktail of determination and confidence with need and desire". It made comparisons with "The Music and the Mirror" from
A Chorus Line, "
Tonight" from
West Side Story, and "Walk Through the Fire" from the musical
Buffy the Vampire Slayer episode "
Once More, with Feeling". "an instant musical theatre classic", and the reason for an "explosive finale" to the pilot. Jarett Wieselman of TheInsider.com comments that the pilot had "as energizing a denouement as [he's] ever seen" thanks to "Let Me Be Your Star", and adds that the song could be "Smash's very own
Don't Stop Believin'", i.e., Smash's unofficial theme song in the same way that Don't Stop Believin' is Glee's. MIX fm described the song as "attention-getting" and "stunning". Scott Brown comments that in the reprise in "The Callback", the song is more suited to the slower tempo, and adds that it "gives those long phrases a chance to breathe and doesn't force them to carry a whole lot of driving rhythmic energy". TV Fanatic notes that in episode 11, "
The Movie Star", Rebecca Duvall's version of "Let Me Be Your Star" was "[appropriately] horrendous", and adds "all Tom and Julia could say was 'great' — ha! And, even that single word pained them to say". JJ comments that she "fails to deliver". Marianne Schaberg of Character Grades said that Duvall's version at the workshop "felt like we were watching a repeat of Lana Del Rey on
SNL. Yikes."
Entertainment Weekly names the song the best song of the series, noting, "The gold standard of
Smash originals, this dueling diva-off capped off the spectacular pilot and set the stakes for what seemed like a phenomenal season to come. Ivy and Karen's powerhouse vocals belied their intense vulnerability as they vied to play Marilyn, and the stunning climax landed them in the heart of Times Square — just two girls with huge dreams" ==Accolades==
