Re: Please proofread my review
Quite good, actually.
Leave a space after your punctuation marks.
You make deliberate use of fragments, which to me sounds very natural, but your teacher may object and require full sentences.
Put the name of the show in italics or quotes.
This sentence is too long - From my point of view the reason for doing such a show have to be the fame and the publicity which are benefical for the their business and let's not forget the considerable amount of money paid by TV channels.
It also has the one g rammatical flaw I saw: "reason.. have." Either "...the reasons have to be X and Y" or "...the reason has to be X&Y "(you consider X and Y completely linked.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
