What's impressive about the movie is that they managed to create drama, artistry and tension in what's fundamentally something you can't really make a movie about because in the end it's just a story of some physicists that successfully accomplished something without anyone really opposing them in any material way.
I think that's laudable and interesting. But if you would judge the movie just based on its entertainment value, I don't think it would score very high. The Barbie movie, which I just saw 2 weeks ago on my TV was clearly a better movie on I'm pretty sure every aspect, and you could tell it was in the first minute.
