> A: めっちゃ好き かっこよすぎ  
>  B: だね  
>  A:あッ 来週ドラマ出るし 見ないとだよ

From the context (them talking about a celebrity), I understood that "見ないとだ"
is similar to "見ないといけない". But when I searched for it online, an user on
<https://hinative.com/en-US/questions/240162> said that it isn't correct
Japanese. Is that the case, and if so, how common is it?

question
grammar meaning sentence anime construction
Is ないとだ correct Japanese?
This sentence is not formal, but it's not incorrect. Sometimes だ can be used
as a sentence-end or interjectory particle, and だ/です can appear after ないと,
なきゃ, かも, たら, etc.
