Interstellar can be a lot more powerful if Nolan focusing in one genre into 85%. But it has 50-50 of drama & sci-fi.

Rating: 8/10 (20 March 2015)

i need to say that nolan still not good as a director. he needs to improve his directorial skill, especially in camera-works, art- direction, and script-writing. his cinematography skill also only reach average level. i can explain in deeper detailed facts about nolan's weakness, but i don't want to. let's just talk about this movie, the strengths and it's weaknesses.
interstellar, by a comprehensive means and it's factual cinematography and writing, was made for people between 17-23 years old. it is clearly described from the movie itself, that this was made for teenager movie-goers. it is not a movie that needs to be studied by professor of movies. it is a movie about nolan's inner creativity which poured into a working-canvas which has only one purpose, to entertain people at that age range, especially people whose sci-fi addict.
the writing. of course for some scenes, interstellar has a good science quote. at first, the writing focusing into a science-basis movie. but too bad, as the movie going, nolan slowly turns the movie and adding scenes which drive the genre into drama-basis. i like the way he made the script, no bad-words or trash-jokes. but in interstellar, he doing fatal mistakes to not focusing in one kind of genre, either pure- sci-fi or sci-fi-drama (which contains more fiction).
if he focusing in sci-fi-drama, he can enhance the storyline into something that connected sentimentally with the ending. he could add some romance or relationship-drama scenes in the middle of duration. so in the ending scenes, the viewers will be shaken by a hopeless-astronout act by hathaway. the ending story is good anyway, maybe it is very good. but it was not bonded by a strong drama.
then if he focusing in pure-sci-fi. i wished he do this because of high amount of budget that really wasted if he didn't sharpen the visual-quality with beautiful art-direction. he waste the budget into something which have a half-drama and half-sci-fi. too bad nolan, you made a wrong move this time.
but i didn't mean to say that this movie bad. this movie is good, but it is only good in the first watching. for the second,third, or the next watch, you will losing your interest, im sure about it. but just watch it guys, it is entertaining at last.
