I have a love hate relationship with RT. I like the site and usually they get things mostly right but there are so many films that are clearly being paid off. Iron Man is one such beyond awful film I think with a rating over 90% which is purely a dream. The script for that film is so bad I wouldn't even know how to write something so corny and obsolete. I know they were following some of the story but the film was just plain bad Hollywood cinema and the raves just kept coming in from the juiced up crowd. I was ready for Batman type awesomeness and got something I will honestly never watch again, not that I watched more than 30m total while fast forwarding through it.
Rambo is another one. I thought Sly did a truly fantastic job with the film and despite some hammy stuff, seriously Iron Man is the very idea of hammy idiocy, the film was true to its roots, had a decent message, and was a kick ass take no prisoners action film like Predator or another of those. It sits at below 40% I think. People are just mindless if you ask me and Hollywood pays most of these people off.
Now saying that, there are some very good reviewers included on that site whom I go to in times of need.
