We saw it last night and pretty much liked it. I don't think it will bring new fame to either Tim Burton or Johnny Depp, but it was OK. The story line started out somewhat similar to the old afternoon soaper, and fortunately the plot moved somewhat faster, but it ended up being comparatively over-the-top. There is a cameo by Christopher Lee and an appearance by Alice Cooper (who looks as old as Barnabas is). According to IMDB, Jonathan Frid (the original Barnabas) is there somewhere, but I missed him.
If anybody gets inspired by this to check into the old series, there were 1250 half hour episodes (!) and a couple hundred (! again) are available to stream on Netflix.
