I just came back from the movie. It's worth going to see if,
1) You don't think you'll be able to go to a concert someday. Hearing the songs with the theater speakers is almost like their concert...and I saw them in Los Angeles and lost my hearing for about 12 hours. The Movie is pretty close to the sound and experience of seeing them. They look especially good on a big screen, and even if you've seen The Show or fancams, you can see details you miss on a computer or TV screen. Most people at a concert have to look at the big video screens anyway because they are so far from the stage....
2) You didn't get to see The Show. The first half of the movie is from The Show, but like I said, it hits different. The rest of the movie has The Show, 2019 tour, and their first concert footage mixed together for each song. It felt like a mini-concert to me.
3) You want to see how much Jisoo adds to each song. I couldn't take my eyes off of her. She also said there will be a 6 year anniversary and and 7 year anniversary to look forward to.
4) You want to get emotional with Lisa. She made me cry with her sincerity and humbleness. In most of her interviews she speaks Thai, which was beautiful. She calls herself a little woman in Thai.
5) You want more YG shade from Jennie. She says she hopes Blinks will get out some frustrations by seeing the movie. I took that to mean frustrations from no new music, but maybe she meant Covid.....
6) You want to hear an extended explanation of music from Rosé and how she approaches it. Jennie talks about her shyness and how she overcomes it to perform.
7) You want an experience with Blinks. I got there late and in the darkness couldn't see how many people were there. I sat up front and was alone. I didn't think more than 5-6 people were there behind me. When the movie ended I was happy: most of the seats above me were filled. Some had their lightsticks. And people stayed all the way through the credits. They didn't want to leave.
8. You want to see the Crazy dancers close up. Their energy really brings alot to the shows.
9) You want to see how hard the choreography really is. You see it so close that you really feel the hard work of rehearsing it. (At least I did; I never thought about the process of dancing before I got into Blackpink.)
Bottom line: even if you've seen a lot of the stuff in the Movie, it just feels and sounds different in a movie house/theater. It really was a good experience. I hope people see it who might not get to experience a live concert.
