I watched it a couple of years ago and found it to be "ok." It has a pretty weak story/plot, not to mention the dialog is pretty mediocre.
Personally I think that if this film is to be on the IMDB top 250, it should be #250. It's really lame to have a sort of "elite" group of movie critics thinking that something is awesome just because it's a little different than other things. Granted that this movie is not bad, it just really isn't that good and it shouldn't be given credit for being "different."
Btw, I put Citizen Kane up there as the #1 of all time if anyone was wondering. Back then, "different" meant something and, without it being "different," the film is a very good mixture of biography with enactment.
