It's called "Duet." It's a musical. It's great.

Critic Reviews for Duet

It is so entertaining and heartwarming, it's easy to look past the nagging plot issues.

An immensely charming and necessary hour of television.

After weeks of dour, angst-ridden soap opera, The Flash is fun again thanks to the sort of format-breaking escapade that should happen much more often.

I'm not gonna lie, I hated the idea of this episode, but I was... wit it after a mere 15 mins.

Forget "Invasion." "Duet" is the real showcase for what's possible when the four corners of the Arrow-verse converge.

Funnily enough I took all of the characters more seriously as they were lit in sepia tones, donned from head to toe in 50's musical garb and were singing about being "super friends".

While 'Duet' is most certainly a musical, referencing as many of the genre's tropes as possible, there's also a real fairy tale vibe to this episode.

It was a legit gem and a highlight for the Arrow-verse.

It's always a risky proposition when a series does a themed episode, but The Flash was as perfect as possible in its execution of its first musical.

It's utterly, incomparably delightful.

Strictly for fans enamored with the thought of their favorite heroes playing Broadway. For the rest of the fanbase, this might be one of the worst episodes of the series.

Come on, this was just fun.
