GP 31: Idol Debut (Engine Sentai Go-Onger)

Idol Debut (デビュー Aidoru Debyū) is the thirty-first episode of Engine Sentai Go-Onger.

Plot
The Go-ongers face a mysterious monster who starts feeding on sound waves upon emerging from another dimension. When the Go-on teams attempt to fight the monster, they only end up enlarging it before it falls asleep. To further confuse things, the Pollution Ministers suddenly arrive to play the song "Gaiark Industrial Revolution Declaration".

Why It Sucks

 * 1) This is nothing but an atrocious stereotypical episode, rather than a "girl power" episode.
 * 2) The plot of this episode absolutely stupid, as either the Gaiark or the Go-Ongers have to sing a beautiful song in order to lessen the extensive growth of Lumbiaco, however, it is a female's voice so what does happen in the episode, The three girls decide to create an idol group which is absolutely stupid.
 * 3) The scene where Yogostein and Kitaneidas decided to shrink the beast by singing dressed as drag queens, and guess what happened Lumbiaco immensely grew larger, due to the awful performance along with an ear-piercing instrument performance, ABSOLUTE NEANDERTHALS!!!.
 * 4) The Rap scene performed by the G3 Princess was really annoying, although the rap itself was pretty decent, however, the actions they were doing in the particular rap was really annoying, and a bit stereotypical towards Japanese idol girl groups as some of them don't tend to do those actions.
 * 5) The fight scenes in this episode were really boring to watch and the mech battle scene was really pointless as it only existed for seconds until the two were de-transformed and were ejected from Gunbir-oh, the fight scene with the G3 Princess was awful, and the Roll Call was really irritating, and the overall fight choreography was very underwhelming.
 * 6) Awful and Stupid Ending, after defeating Lumbiaco, Saki wanted the three of them to fight for justice as their newly formed group, only for Kegareshia to leave them stating she only wants to dirty the Human world, and walking away from Saki and Miu returning to the Gaiark Hideout, and hearing the worst dialogue from engine BearRV, stating that Kegareshia is an idiot for returning to her evil roots (our heroine ladies and gentlemen).
 * 7) Not only this was the worst episode to exist in Go-Onger, but this is also one of the worst episodes created in the Sentai franchise. Only behind these episodes.

Redeeming Qualities

 * 1) As stated above, The G3 Princess rap was pretty decent, if you ignore the actions they were doing in the rap.
 * 2) Hiroto's outstanding performance in the episode.
 * 3) The third and final girl power episode, GP 38: The Maidens Sanctity, is comparingly more tolerable than this episode.
