I think you can be theatrical without being obnoxious. It's not like I hate all choreography or think she should just stand there all the time but these were just...really stupid looking.
It's definitely unique (or at least, I personally haven't seen any other musicians performing similarly) - the first time I saw Taylor perform was at that iHeartRadio performance last year, and wasn't sure what to think of it (the hands and the gesturing and posturing etc.). I decided that as long as she's the only one doing it and it doesn't become standard for everyone, I'll like it/am okay with it.
It's (the only thing, maybe?) what I like about her.
