Opinions are like assholes...everybody has one. You are entitled to your own opinion and I wont trash you for it.
I for one like some of his movies and understand WHY he did the majority of them. The disney movies he did because of his kids. He, like a lot of movie stars, wanted to do movies that his kids could watch. I am an aspiring filmmaker and run my own online web show. I look at movies differently than the general audience. Lets look at his movies...
"Gameplan" was a good family movie. Rock was right at home playing a star football player.
"Tooth fairy" was crap.
"gridiron Gang" was a good, wholesome true story. I happen to like those type of movies and I thought he did well in it.
"Walking Tall" was ok.
"Be Cool" showed that comedic side of him. Good for what he was involved in, but the movie sucked.
"The Rundown" was AWESOME. Loved every minute of it. Again, showed his comedic side.
"Doom" I loved. Rock was solid. Not the best script but the way it was shot was good.
"Faster" I skipped because I heard the reason the movie fell flat was lack of story and advertisement.
Loved "Fast Five", "The Other Guys" (his cameo role was amazing), "Get Smart", and "Southland Tales". "Race to witch mountain" was ok.
Im looking forward to "G.I. Joe 2", "Snitch", "Pain and Gain", and "Fast 6 & 7"
Yes Dwayne has made a name for himself. He might not ever win an Oscar for his movies (there are a ton of people that haven't in Hollywood), but he IS an A-list star.
Dude Seriously. I like some of the movies "The Rock" has done but let's not fool ourselves here. Dawyne "The Rock" Johnson has never done a movie where he is not playing himself in some sort of fashion and you know it works for him but I don't think you will ever see him in a movie that actually requires acting because the sad simple fact is he can't act at all. Let's look at some of those movies he did another way.
The Gameplan - He used to be a football player and he is a father so acting wise this isn't much of a strech
Gridiron Gang - As I said before he used to be a football player and he's playing a football player again not much of a strech for him
Walking Tall - Most of the movie required him to beat the crap out of people which really doesn't require much acting
Be Cool - Liked his charcter but in the end that movie had so much star power it would have been good with or without him.
The Rundown - Most of that movie also required him to beat the crap out of people and when he did speak he really wasn't that funny also he had better actors to pick up the slack
Faster - Again he plays a guy who beats the crap out of people. The only thing that saves this movie from being a total piece of crap is Billy Bob Thornton
Doom - Aside from the action scenes that movie was just an awful piece of crap and nobody did any acting in that movie
I fell asleep about 30 minutes into Southland Tales
Race To Witch Mountain - He played another tough guy role that didn't require much acting
Fast Five - Didn't really need him because it had Paul Walker and Vin Diesel and a bunch of other well known actors in it also he plays another tough guy role that dosen't require much acting.
The Other Guys - Yet another tough guy role plus it had Mark Whalberg, Will Ferrell and Samuel L. Jackson in it plus I loved Michael Keaton in it
Get Smart - Surprise, Surprise yet another tough guy role plus it had Steve Carrell, Ann Hathaway, Alan Arkin, James Cann and Bill Murray in it
G.I. Joe 2 Has Bruce Willis in it so I don't think it's going to be a problem selling it and again Johnson plays another tough guy in it
From what I read about Snitch and Pain And Gain he plays tough guy roles in those movies as well as far as Fast and Furious 6 goes from what I saw it's going to have Vin Diesal, Jason Statham and Paul Walker in them so I don't think his performance is going to make or break those movies.
You forgot to mention The Mummy Returns (which at the time already had a star studded cast before he came along) and The Scorpion King and even in both those movies he had tough guy roles.
I'm not going to say Cena is a better actor than "The Rock" because honestly neither of them are really very good at acting but I will say that at least Cena is trying diffrent ranges in his choice of movies. He has tried action movies, a drama or two and a couple of comedies so unlike "The Rock" he is not trying to play different versions of himself
