First, I really like war movies like Saving private Ryan, Apocalypsis Now or The thin Red Line. Second, 1917 is a pretty good film with an excellent cinematography. Third, the camera work and the only few CGI effects are amazing too. But, on the other hand, the script here is not quite original and the storyline is quite weak. To add, some scenes looks like unrealistic or unbelievable. So, overall a pretty good war film but not a masterpiece like Saving Private Ryan. Enjoy.
