1917 is a good movie but to say it's incredible is a bit exaggerated. Visually it's very good and the Oscar for that could be justified even though there were many other movies for this year that could have won that prize. But yes the cinematography was great, as was the soundtrack, so that alone makes it already worth a watch. The story on the other hand has flaws, and not little flaws, some scenes don't make much sense and that's why it's not a great movie but just a good movie. The acting was good, the cinematography great, the sound effects on top, the story (what to me is the most important in a movie) was just okay but not great. I saw much better war movies that got lesser credit so to me it's slightly overrated, but in doesn't change the fact I did enjoy watching 1917.
