I have a question for Dali fans *Spoiler*

Hey I thought this movie was kind of slow but there were a lot of parts that touched me & I think the acting was outstanding. Javier Beltran was seriously amazing & I was in tears at his fate. He really made you care about Lorca. (I knew nothing of the characters before seeing this movie) My question is for hardcore Dali fans. I want to determine whether Pattinson's performance was authentic or not. I'm not talking about his looks or accent. I'm talking about his mannerisms, his facial expressions, & the inflections in his speech patterns. Was that how Dali really behaved? Was the performance believable? I've watched a few videos of Dali but they are all of him in his older years & it seems Pattinson did him justice. From what I've seen & read Dali was an eccentric provoking man, yet shy & captivating. Please I'd like to hear from true Dali fans how they feel about Pattinson's portrayal. And please don't say 'oh i hated him cuz he's from Twilight.'
