Already from the poster..
..you can see how crappy it is. Come on, I have hardly used photoshop and I'm not the best photographer or designer, but I would have made a much better look than this. First of all, in that kind of cheap look, a fancy superman-logo just doesn't fit. A more regular looking logo would be more fitting. And the round-faced man is obviously acting (!) to look down. I mean how can you fail that?? It's a horrible background picture, and how can you think you can get away with making five, yes FIVE different fonts in different shades and colors on the same poster? And the ugly layers with clouds and everything. And to highlight a bunch of names noone have heard about? This doesn't belong on imdb, this belongs in the homes at the people involved with this.
Ok, maybe they use the same font on the names on the top and the name-text on the bottom, but that's impossible to takenotice of when there are different tacky designs on all of the text fields. And it looks like the man is not photographed towards a greenscreen, but rather being cut roughly around in paint, or probably printed out, cut with a scissor and glued on to the low quality photo of the skies. And what's that line of fading fog over the title and logo?
There is no natural element to draw your eyes to as it should be. All the elements are too visible and too flamboyant for that. It's a circus!
But who am I to judge a movie on it's poster. It might be a masterpiece. lol
Sorry for making you shout troll to the screen now, but I see what I see, and I read my own standards into this. I'm not professional, but I feel like it when I watch this poster.
