I don't always agree with him, but when Movie Bob does do a review I agree with, it's an occasion to remember:
On the ending of Ghostbusters....I liked it, actually, but agree with him in the sense that it lacked a certain gravitas that the original had (ancient evil god bent on destroying the universe vs. angry nerd warlock bent on opening the gates of the afterworld to ...um... destroy the universe).
MovieBob has his own blog here. Check it out! I agree with him about 20% of the time, but his arguments for and against movies are at least well-reasoned and cogent.
