For me it all depends on what I'm looking for in a movie. Different movies bring out different expectations for me.
If it's a drama/thriller/mystery, the plot, and subplot are the most important parts for me. After the plot, it's the acting, not necessarily who's acting, but at least be good enough to make me identify, or interested in the character that's being portrayed. Then it would be the directing, if the plot is good, and the acting is good, but the direction is poorly put together, the movie is doomed.
If it's sci-fi/adventure, the plot at least has to be interesting. Depending on what type of sci-fi/adventure it is chances are it's out of the realm of possibility it could happen, but I'd like the movie make me believe that it could. Then the special effects, sound, costumes, and camera angles, and action sequences come into play.
If it's a horror movie, depending on type, I'm not looking for too much but shock value, and gore (slasher films). For the spiritual/supernatural, it's the plot, and characters.
Epic/biography, I'm looking for the story to be as close to the real thing as possible, then the acting of the lead actors, and actress', to see if they can make the subject of the story believable, followed by the directing, I need to know this guy did his homework, and that he can capture the feeling of the era. Lastly, would be the costume's, and hairstyles. Very big for me in these types of movies.
Love stories, I'm looking for plot, chemisty, and the actors being ability to make me believe in the story that's being told.
Remakes, I'm looking for an improvement over the original in all areas. If you can't make it better, why touch it?
Animation, good story, good animation, and nice soundtrack.
Musicals, just give me performers, that can sing, and dance, with a good story as a follow up.
NICE
