Sheldon receives a message from his best friend in high school, Tam Nguyen, that he is coming to California to show his son around Cal Tech. Sheldon's closest group of friends wonder why Sheldon has never mentioned Tam before. The reason?: Sheldon and Tam have not spoken in twenty years since Tam is now on Sheldon's enemies list, because, according to the list, Tam "knows what he did". As such, Sheldon has no intention of meeting with Tam. While whatever the issue, Leonard, Howard and Raj believe that the reason will be nothing material to any normal person and thus without even knowing what it is, already side with Tam. After going through several channels without finding out the reason, Leonard, Howard and Raj do locate Tam on campus to find out directly from him, Tam who doesn't divulge why for a very good reason.

Sheldon Cooper: Howard, today is your lucky day. Leonard's out, you're my new best friend. Well, I'm not thrilled about it, either, but here we are. Okay, fine. Is Bernadette there? Sh... no. Just Stuart? Let me call you back.
Amy Farrah Fowler: [he hangs up] Let me guess. This thing with Tam escalated, and now you're mad at Leonard and looking for a new best friend?
Sheldon Cooper: You know me so well. It's too bad you can't be my best friend.
Amy Farrah Fowler: I can be.
Sheldon Cooper: Oh, you can't be my wife and my best friend. Who would I complain about you to?

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 Tam Turbulence

Few one-liners coming from Helberg are bang on the bucks while not only the rest of the subjective procedure is dull but the concept itself is too shallow to hold its own grounds; a total blunder.
