I realize that Inglourious Basterds received lots of critical acclaim, and it has some of the most intricate dialogue I've ever seen in a movie. But honestly, in my own personal opinion? Captain America is a far neater, better structured story and piece of entertainment.
I actually think Basterds' story structure was rather lousy, and that the writing was very undisciplined and indulgent. You could just tell Quentin was having all the fun he could with his word play. Which appeals to certain people and it's fine if they like that. But Basterds is a movie where the first 25 minutes consist of the villain and some nobody sitting at a table talking about crap. Where a good half hour if not more is spent on a few of the Basterds messing around inside the tavern. The movie wasn't really even that interested in moving along and telling a story, and its "story" consisted of maybe 4 or 5 main scenes that were really dragged out.
Also, I hated the protaganists in that movie and found them unsympathetic and lacking in humanity. God, Brad Pitt tortures a female teammate by sticking his fingers in her bullet wounds just because he mistakenly suspects her of wrong doing.
Just my opinion.
