Comparisons - Usage of than he/she

[archu.mohan]

The "Comparisons" Chapter in the MGMAT guide provides the following examples:
You are more interesting than he.
You are less interesting than she.

I am generally used to hearing people say "You are more interesting than her/him". I am curious if this usage is grammatically incorrect?

Thanks much!

IMO, this is incorrect

A complete sentence should have subject, verb and object...

You(Subject) are(Verb) more interesting than he(object).
You are less interesting than she.

In above two statements, instead of he and she, it should be him and her. The reason behind this is....he and she are subject pronoun..but the statements should have them in the form of objects and that's hy him/her is correct.

[Sankeerthana]

A complete sentence is one which contains a subject an verb and expresses a complete thought. A sentence does not necessary have to have an object to be considered complete. E.g. "He Drinks" is a complete sentence.

In this case he and she is the correct form of the pronoun.

Even though the other form "him" is common colloquially, the possessive pronoun is not correct here. If you want to be sure, flip the sentence

You are more interesting than he (is). --Correct
He is more interesting than you (are). --Correct

You are more interesting than him. --Incorrect
Him is more interesting than you. --InCorrect
