Tower Heist did not heist my attention

I had not the pleasure of seeing Tower Heist today. Expected it to be one of the best movies I've ever seen with H-wood veterans Ben Stiller and Eddie Murphy. Turned out to be the biggest overstatement of cinema history.
  For sure Brett Ratner, known for the Rush Hour films, directed the movie brilliantly. But the screenplay but Ted Griffin and Jeff Nathanson  managed to deliver a plot, a proper story but failed in the comic factor. The characterisation was boring. I'd get more laughs watching a Japanese ad for McDonald's.
   The jokes were confusing - I couldn't tell when one was being funny or not. Eddie Murphy's role didn't suit him. Unlike Jamie Foxx as MF Jones in my favourite comedy of all time Horrible Bosses. I've wondered whether the writers were inspired by his role in designing Murphy's character.
  The movie is rated PG-13 and rightfully so. It's about 3 employees of an exclusive apartment building who lose their pensions in the Ponzi scheme of Wall street business Arthur Shaw played by Alan Alda. The group enlist the aid of criminal slide (Eddie Murphy) and some others to steal their money back. Alda's performance was the best although you could say no one else sparked prominently in their own roles.
  The film gets a 2 out of 4 from me.
