A person either loves 50's sci-fi and horror movies or they don't. There's no middle ground.
EDIT: This was in reference to some not liking that movie posters & movies of the time didn't always sync up or may not be as fast-paced as modern films.-Innuendo
Ya know... I'm not entirely sold on the modern (faster-est paced) movies are better to be frank. The 50's flicks, while a tad corny, did rely on a suspenseful-ly told story and the viewers imagination to (best) fill in parts that would today just be gushing gore. Because nobody knows what really scares us better than we do (kick in imagination->done).
Moving forward the story telling craft became (much) less important as movies went from thrill-a-minute, to action packed, to violent, to really violent, to ultra violent, to hyper violent to who the hell knows what's next. It's gotten to the point where there is so much going on so fast that one spend half the movie pondering wtf just happened. Why?
In the 50's when a scene was shot "at night", the picture would (more often than not) just have a grayish background (that we all understood to mean it's night time), and the rest of the "action" was easy to perceive including the stick the rubber monster was mounted on. Now we have scenes the cost millions to create, but are so dark that the screen is literally completely pitch black with only a few points on reflected moving light, and nobody could possibly have a clue what happened. Half these "High-Tech" million dollar scenes could easily be recreated with a cheap camera, a rubber monkey, and the minimal light that leaks under a closed closet door for under $10.
So if you're looking for a superspy, rockstar, scientist, brain surgeon, astronaut, racecar driver ... look no further than the Adventures of Buckaroo Bonsi - It is by far the stupidest movie I ever totally loved (I still whistle the rather catchy theme music from time to time).
