Quentin Tarantino

Yes. His movies are completely entertaining, without trying to be some arty crap. Also, the music and sound work in his movies are great. Costa Rican.

Yes. The answer to your question is in his movies.

Tarantino's films have garnered both critical and commercial success. He has received many industry awards, including two Academy awards, two Golden Globe Awards, two BAFTA Awards, the Palme d'Or, has been nominated for an Emmy and a Grammy, and has been named one of the 100 Most Influential People in the World by Time Magazine in 2005. Filmmaker and historian Peter Bogdanovich has called him "the single most influential director of his generation".

Never really like the films I've seen. All I keep hearing is that his movies are good but no one says as to why they're good.
I know he has foot fetish.

hmmm... "big deal"... no-ish, but I love most of his stuff, and definitely he's influenced movie-making with his over-the-top style.
basically, he's legitimized the standard "exploitation" catch-all-genre of film into the mainstream. so if that's a big deal, then yes.
I'm American.

I think so, because not only are his movies invariably awesome, he's a weirdo. He doesn't behave like your stereotypical Hollywood star, and I think he's refreshing.

Not many that I know enjoy his movies, but I do and that makes him a big deal to me. I'm from Germany.
Loved him most in the 90s with Pulp Fiction and all, didn't enjoy Kill Bill so much and he faded a little from my memory until I was taken by surprise with Inglorious Basterds and Django. I just love his calm dialogue driven style he does with some nice Over-the-top action inbetween and have it pay off but he is one of those that can do it, so that's a big deal to me since I derive so much pleasure out of it.

He's made some great films and some terrible ones. Django Unchained is definitely my favourite, but I think the actors rather than the director, were what made the film so good. On the other hand, Kill Bill is literally just a mess.

He used to be, not sure anymore. People get old.

Yes, he's a world famous film director and by default I think that makes him a big deal. He's hugely succesful in his chosen field, and his field happens to be an extremely popular form of entertainment. I'm British.

I watched Pulp Fiction yesterday and kill bill series before that. Have to say he got better with time, but what i noticed is, he keeps a scene with ridicolous dialogues which normally other directors wouldnt put in the edit. Story doesnt go past, present future, but more like section and section and have to say that reminded me Virginia Woolf a it. Some parts of the movies are corny as much as old japanese movies, dying scenes etc.

While the only one I watched was Pulp fiction (and even then,it was an unofficial script reading).It was pretty entertaining and very memorable.
I'm Gondorian (Deep south American >.>).

Only kinda. I'm not a personal fan of his films but a lot of people are. You'd like them if you're a fan of gritty action and dark humor.

I think he's overrated, but then again I think this about most directors whom are popular (posting from the U.S.)

He's in his own movies some of them.

Pulp Fiction. Nuff said.

Greetings from Sweden.

Quentin Tarantino is a great director that apart from Pulp Fiction, has no style of his own. Every movie he has done not called Pulp Fiction is based off previous styles that are currently influencing him. I love his movies but that's just my opinion. Christopher Nolan is a great director that has his own style yet is terrible at 3rd acts. Each to their own.

To answer your question though, yes he's a big deal. Australia.

Yes. why? He is the master of plot twists and easter eggs. watch this: http://www.youtube.com/watch?v=op4byt-DtsI

ps: you can start watching at 3:00

Germany

UK, yes he is a master. Some of his films are so good they are off the scales. As for Django Unchained, even I wasn't prepared for how much I enjoyed it.

I don't know if I'd say he's a BIG deal, but he's a well respected director.

United States.

He's all'right... i prefer takeshi kitano thought... with movies like brother.

No nationality.

I like most of his movies.
Pulp Fiction, Reservoir Dogs, Jackie Brown, Django Unchained to name a few.
Never liked the Kill Bill movies (and to some extent Inglorious Bastards).
The co-movies with Robert Rodriguez aren't that bad either. (Grindhouse)

He makes fun movies. All his movies have violence, blood and gore without making the violence violent, but it was rather like making fun of violence. The lines and characters in the movies are great and memorable. I think he's a big deal because he makes his movies distinctly his style.
