Agreed and especially co-signed with that part. I'm sick and tired of people excusing crap or mediocre filmmaking by saying "Well it was never meant to win an Oscar" or "If you go in expecting Casablanca...." type of logic.
A movie doesn't have to be dumb, formulaic, insultingly lazy and offensively stupid to be entertaining. The "you have to shut your brain off" argument holds no sand. The best popcorn movies engage you at both and that is what makes them so delightfully entertaining. Jaws, Star Wars, Indiana Jones, Back to the Future, Terminator 2, Jurassic Park, Spider-Man, Iron Man, Pirates 1, etc. Even this year you can watch something like X-Men: First Class or Super 8 and feel engaged by the movie. That is why they're such a pleasure to view. If TF3 is anything like TF2, it will just be explosions, CGI, indistinguishable robots hitting each other and mildly offensive ethnic stereotypes for 2 1/2 hours (or now under 2 hours, so I guess Bay got some of the backlash). I don't get why people who generally despised the last one and realize the first one is pretty boring are so willing to shell out at least $20 for a few tickets when the next one comes rolling by.
