Of course they do, but gamers aren't paid to give them, she is. If that was my job I would make sure I explained myself with thorough consideration, and if it isn't possible to verbalize it, I won't give it. Simple as that. 

I just read his post twice and at no point did he say she was not allowed to have an opinion, so I am confused as to the purpose of this post.

There is a difference between 'family' entertainment and 'childrens' entertainment.  Aside from the gameplay both SMG2 and R C have which she had no issues with the R C series has a fair bit of story to it with a few sly adult jokes now and again that a child wouldn't pick up on, because it this it can appeal to older audiences while still being child friendly.  SMG2 has none of this, it has pretty much no story, no adult jokes (the characters don't even speak and just makes noises) and the little story it does have is presented in a very child like picture storybook manner.

R C and SMG2 are two very different games.  Mario relies purely on gameplay but R C has gameplay and also a story to entertain along with it.

She basically said last year that Ratchet & Clank:ACiT was the best platformer in a long time.

The graphical advancements of the Ratchet & Clank franchise is great. In fact, I would go ahead and refer to the most recent R&C game as pixarlike quality (if not all of the PS3 versions of the series). The story had both happy and sad elements, which led to the game being very much story driven. The gameplay was varied and they completely changed the mechanic to Clank levels from previous games. Of course I'm sure that most people on here who are blasting the series haven't touched the game since the PS2 (if even then). That or they are just talking shit because of Morgan Webb and her "hypocrisy." Which I find stupid due to the fact that people don't seem to understand platformers are just like any other genre.

If people like Call of Duty, that does not mean they will like Battlefield. If people like God of War, that does not guarantee they will like Bayonetta. If people like Oblivion, it doesn't mean they'll like Fable. If people like Star Ocean, that doesn't mean they'll like Final Fantasy. Again, I repeat, it's about OPINION. e.e

Uh huh, so are you going to apply that same criticism to:

Killzone

Halo

GTA

MGS

Gears of War

Uncharted

Tomb Raider

Call of Duty

Guitar Hero

Of course you won't. 

The argument that Mario Galaxy 2 is an add-on type game to the first one... Pu-lease.

You mean it's not the same for Modern Warfare and Modern Warfare 2?

God of war 1, 2 and 3?

Ratchet and Clank Tools of Destruction, Quest for Booty and A Crack in Time?

Shall I go on and on?

The entire rant about Galaxy 2 is completely devoid of logic and seems to me like it's more a vendetta or agenda against Nintendo than anything else.

Did watch her criticisms of SMG2? It was entirely about the cartoony graphical style. That's what makes her a hypocrite. You seem to have completely missed my point. R&C is a cartoony game. If she had been complaining about SMG2's gameplay and not it's graphical style then you'd have a point. For example,  if I said I don't like Tekken 6 because it's a one on one fighter but listed another one on one fighter Super Street Fighter IV as my favorite fighting game I'd be hypocrite. That's essentially what she did.

that last sentence is baseless and ridiculous. something against nintendo? i'd see that point if she herself gave the reveiw or said the gameplay was bad but she didn't. i think you took it to far. she doesn't haft to like how it looks. and as for the comparisons to the other games. point well taken.

but referencing other games is not going to help your argument. people reveiwing MW@ and GOW 3 have aready said mostly nothings changed.

it's sad when the day of the  OP dies.

There is a great quote... by some famous author.

It goes something like

"When I was a teeneager I secretly read fairytales without people seeing me to pretend I was more mature, and when I was older, I read them in the open because I was mature enough to not care what people think."
