I honestly thought that this movie was decently good. I was a little confused at the very end with Ke$ha, but overall it was okay. I thought that the acting could've used a little tweaking in some scenes. Especially when Jerrica was talking about her Dad. Also, so before I watch a movie, I look up the cast. I will say, WOW! There were a ton of famous people in this movie. Ke$ha, Chris Pratt, Molly Ringwald, Alicia Keys, Jimmy Fallon, Dwayne Johnson, etc. But on Google, it said that Ariana Grande was in it. I was expecting her to be in it when all the celebrities were talking about Jem, but no. So if you are like me and look up the cast before watching movies, Ariana Grande is NOT in Jem and the Holograms.
Overall I would rate this movie an 8/10. I would only recommend it to music lovers though because I know there are people out there who don't like movies where they are performing. Anyway, please watch it if you are a music lover!
