while i think i preferred Gaga at the start with her more simplistic video's she's gotten WAAAAY too out there and famous too early on! i loved her and now i just find her good for background motivation music. i bought The Fame by Just Dance alone and thought it may or may not be a hit when i bought it, then later of course i ordered The Fame Monster which is better in terms of the material quality with some simplistic but hitting songs.
but after Bad Romance overhype and Telephone's overkill i kinda unfortunately went into hater mode, but now i think on a bridge..she's Marmite really, but i hate it when she has good music but her video's reflect a lack of originality when the concepts sound so great!
but i did think there was a Hammer Horror vibe with Alejandro which was pretty cool, but dragged on a bit which was a shame :/ also i liked the Madonna references being a fan of Madonna myself
but i still have my faves Dance In The Dark,Alejandro,Teeth,Paper Gangsta,Brown Eyes and LOVEGAME
like i said she's marmite, and just as famous

but i think every artist is to be honest.
