I remember when Basterds first came out, I narrowly missed watching it in the cinema because I wasn't 18, but I was when the DVD was released. I had heard good things - a WWII movie with a Tarantino spin; "yeah, they basically come up with this plan to assassinate Hitler", my friend said to me who had seen it before. In a nut-shell, yes, that's an incredibly easy way to describe Inglourious to someone who hasn't seen it before but it is so much more.
It is a ride from start to finish; extravagant in it's plot execution, larger than life characters, humourous and liberal with it's violence, anything less would feel like you've been sold short in a film where it's basic plot is for a group of soldiers to kill Hitler. You need everything else to be as outlandish as the story and Tarantino knew this.
Everything from the incredibly suspenseful opening and introduction to Christoph Waltz's infamous Colonel Landa which involves Landa visiting a French farmhand in order to find a hiding Jewish family to Brad Pitt's rag-tag bunch of soldiers who travel to occupied Europe in order to kill and scalp Nazis and later assassinate Hitler and thus also allowing the rest of plot to unfold.
Everything comes together to make Inglourious, if any one aspect was anything less, it wouldn't have nearly of worked half as well as it did. Inglourious is a Tarantino film and if anyone else had tried to make it, they would have failed. I enjoyed Inglourious the first time I saw it and I still enjoy it today.
