Contrary to what some people say, I believe this sequel to "El otro lado de la cama" is much funnier than the first. I must confess I've seen both films in different order, first I saw "Los 2 lados..." and then I saw "El otro lado...", so maybe this has to do with my preference as I think it affects how the viewer reacts to the sequel. I had no idea what the first movie was about, so I watched this without prejudice and no back story, and I enjoyed it immensely. The gags are always funny, specially the ones that have the men in them, as the story lines for the two girls are the most boring, they don't really have much to work with. So, contrary to what happened in the prequel where both men and women enjoyed the same status in the movie and all of them had great lines, in this one all the weight of the plot sits on the two main actors, Ernesto Alterio (a favorite of mine) and Guillermo Toledo (a very talented Spanish actor). Even Alberto San Juan has a great role in the film and displays some of the funniest lines (my favorite: "España se acaba" which means "It's the end of Spain"). The cast is excellent and these are some of the best Spanish actors around (even though Alterio is Argentinian). I think the music numbers are far better than those of the prequel and the songs more recognizable (80s Spanish hits that bring good memories). I enjoyed the plot in this one better than "El otro lado...", i think Pedro and Javier are such a funny couple, competing all the time for girls, its almost ridiculous but their relationship is always hilarious. They will also find something about themselves that hadn't suspect before. All in all I enjoyed the sequel a lot more than the prequel which was a bit of a disappointment. You don't need to have seen the first one to enjoy this, it stands as one film alone. I highly recommend it, you'll have an hysterical time with it and the cast is gorgeous.
