I genuinely love the series and therefore i believe this film shouldn't have been produced .the concept they pushed in the film might have worked better as a series but still ...the whole time travel trope was completely ruined in this one. Yeah it has a happy ending but it was at times confusing, cringey and painful to watch .This is coming from someone who genuinely loves the cast and would watch anything with Greg in it.Best advice id give is just watch the series only.My love for Greg and the ShiShis music in the series will forever be in my heart though.
