I don't get it

Rating: 7/10 (2 April 2015)

This may probably be my first review over IMDb (even if I'm looking at reviews and ratings all the time) but I can't let this go:
Interstellar may not be the best movie of all times but how the hell can you be demolishing this movie as you do?
This movie brings, which is the main goal of movie, entertainment. If you want science facts, watch documentaries. If you want SciFi, why don't you stick to books (intended to make imagination work far beyond a movie would do) instead of watching a movie?
This movie brought me, during a bit more than two and a half hours, in deep space and time. It even worked so fine I didn't even notice it was so long.
I was totally convinced by this movie even though I noticed the gigantic, not to say cosmic, plot holes (the NASA stuff, the main attitude of Matthew McConaughey and so on). But at least, it made the job: it ENTERTAINED me and brought a little magic with this cocktail of space travel and time.
But I can't stand reading these completely unjustified negative reviews made against a movie that sincerely does not deserve such hate. I'm wondering if, as complained for very positive reviews over-rating the movie as a marketing plot, the main goal is to lower down this movie to keep others on the top.
Interstellar is, again, not a masterpiece but totally worth watching for those who'd like shipping through space (not to say dreams) for 3 hours.
