After completing a survey to find out all they need to know about each other, Raj is going on a date with Anu, the woman his father set him up with. Despite Anu not quite being the type of woman he usually goes out with, desperate Raj may forgo his dream of romance solely to be married. Even before taking some of the survey themselves, Leonard and Penny already know that they are not the most compatible couple. But their answers to one specific question may place an impassable wedge between the two of them. While Penny and Raj turn to Bernadette and Howard with their problems, Bernadette and Howard can't understand why their friends wouldn't just take their sage advice. And now that Stuart and Denise are dating, Howard ad Bernadette aren't sure if they can handle the fact of Stuart having sex in their house. Written by Huggo

The Big Bang Theory

Almost a cultural hub and a dream project for the nerd and movie goers out there, The Big Bang Theory lift off from the first episode in '07 possibly breaking many records on broadcasting and awards shows; this is another one of Chuck Lorre's production as it too resembles with the others on its hardcore and counter argumentative humor. And unlike others, its witty and sharp humor doesn't walk on 'mundane sitcom rituals' which they carried off till the mid series quite nicely after which the plot grew thin and the humor got petty and childish to a point where the viewers have started to feel like a homework that doesn't end.

On performance level, Parsons is never reliable on his co-stars, he is literally a one man army and the reason behind it is not that he is given the range and content to flaunt his skills but even when the writing goes frizzy in its latter season, he delivers unflinchingly. On the other hand, Galecki is convincing throughout the series along with Helberg supporting him decently.

The narrative that was once fluid, gripping and thought-provoking has now turned into this misconceived mixture of rotted out ideas, that ought not to draw even a chuckle, let along be intriguing enough to keep the audience tangled in these undercooked characters' mundane life.

Another main reason, why the ideas narrowed down as it aged on screen was because of too many lead actors sharing the screen and the writers being restricted on offering and dividing the work or humor to each and everyone resulting into low quality of the final product. Even though the series have somehow found itself in the 12th season it still hasn't offered much on character development (their work on Sheldon is appreciative but not worth the effort).

Season 12

With an attempt of attaining a closure to a higher ideal, the last season is sculpted to justify and culminate the entire series and as much as the hopes are higher, the maturity on writing is equally lower where the offered final product is of a daily soap quality.

The Procreation Calculation

Helberg and Rauch's salty relationship somewhat elevates the sinking episode that is more soothing than entertaining or funny, but the rest of the act is overdone just like Bialik's portrayal in here where even Galecki's expressions can't save it.
