re: Were the early Horror Movies Scarier than the ones Nowadays?

Not really, and before people break out the pitchforks and torches... much like every other genre of movie when we think about older horror movies we remember the classics, not the turds.

Whether you show the monster, don't show the monster, show the monster taking a chainsaw to Linnea Quigley, or show Linnea Quigley taking a chainsaw to the monster most horror movies, like most movies over all, are going to suck. There is a vast horde of really bad old horror movies.

Get a good director, a good script, good actors, and as a few horror flicks have shown recently you can come up with a good movie.
