I like to go back and watch SomecallmeJohnny's let's play of the E3 demo now and again, the man knows and loves his Igavania games.
He even finds a secret room that almost everybody else misses in their playthroughs of the demo. And his reaction upon seeing the boss is priceless
More people should check out his stuff, he's reviewed most of the Castlevania series on his personal channel, and played a lot of the games for commentaries and let's plays over at the youtube channels BrainScratchCommentaries and Super Gaming Bros.
(The C:SotN commentary on BSC is an old but good one, especially the part with Galamoth, all I'll say about it is "And then he died")
