No Strings Attached, Friends With Benefits...Whats the difference? REALLY?!

Okay.  This is only my 2nd post and here I am already writing about 2 movies that I have never seen and will save until a 2am cant sleep so lets get this over with marathon.  We have all seen the trailers for these movies, we know the stars are established actors and know that both female leads are both extremely talented and beautiful (VERY DIFFICULT TO COME BY IN TODAY'S STYLE OVER SUBSTANCE SOCIETY)...and we also know how each movie is going to end.  This formulaic crap is the reason that many movies from Hollywood lose truckloads of money: we know whats going to happen before we plunk down our hard earned money!!

Dont believe me?  Watch this:
Man and woman are friends.  Both have crappy luck dating people or realize that they dont have the time to get to know someone because they are always working.  During a conversation at a bar or dinner or at a wedding of mutual friends they decide that they can do without the relationship and what they really want is sex.  They then say, 'hey I find you attractive and you find me attractive so lets have sex without the commitment'.  Both agree and they spend the next 5 screen minutes in a montage of positions and high fives.  Afterward they are each told by their respective friend groups that it wont work but they refuse to believe it.  Then they see the other with a date and get jealous.  The woman cries, the man fights, they realize they are meant to be together and its another happily ever after.

If I am wrong, PLEASE TELL ME.  In the meantime I will continue...

My problem isnt only that these movies are made but its also that people will go see both of them EXPECTING them to be GREAT.  Come on, people!  What about either title, description, or trailer says to you 'this is going to be a good movie worth paying at least $8 per ticket for?  NOTHING!  I am a HUGE Portman fan and thoroughly enjoyed Kunis in 'That 70s Show', 'Black Swan' (of course), and even in 'American Psycho 2' (yes the movie SUCKED but she played it very campy which made it watchable) but there is no way that you can convince me that either actress can make those movies anything close to classics like 'When Harry Met Sally' or 'Sleepless in Seattle' because the plot isnt there for them to turn into cinematic gold. 

Please, for the love of everything that is holy, stop watching crap like this!  I respect the fact that actors need to make money because independent movies with great plots that also pay well are few and far between but maybe if we stop going to see this stuff Hollywood will allow better written movies to be green lit and thus provide movies to the masses that have excellent plots while also allowing actors and actresses to see the type of paydays we all dream about.
