Putting aside possible (or not) historic accuracies, and I guess about up to 98% of the events depicted here are imaginary, this movie a simple poetic view of the one small (but nevertheless significant) part of the WWII. Nothing more, but also nothing less. Some musicians being 30-odd years in professional business also undertake practice, and so does Mr. Nolan. This is just it. He could have made another Saving private Ryan, but he didn't. He just explored movie making possibilities combining three simultaneous "stories" from three different points of view and, also keeping in shape. I like this movie. It's a bit unusual, personal, full of beautiful details and bits, emotional, poetic. No, not a spectacle. If you expect such a thing (with everybody shouting, shooting, running, explosions, screams and the works), forget it. However, if you're in for some delightful cinematic experience, you're welcome to watch and enjoy. Also, mind the soundtrack by Mr. Zimmer, who is not so inspired so often. And the length of the movie is just about right, maybe one shot too much (at the end), but that's a director's editing choice.
