Um, being as I know a little something about movies and cinema and the movie making process, I can assure You that Micheal Bay, like or hate his movies, is considered quite the successful filmmaker.
Technically he's only directed 7 big budget movies, those being -
1.) Bad Boys (1995) - $23 Million to make/$141 Million World Wide
2.) The Rock (1996) - $75 Million to make/$133 Million World Wide
3.) Armageddon (1998) - $140 Million to make/$554 Million World Wide
4.) Pearl Harbor (2001) - $151 Million to make/$450 Million World Wide
5.) Bad Boys 2 (2003) - $130 Million to make/$272 Million World Wide
6.) The Island (2005) - $120 Million to make/$161 Million World Wide
7.) Transformers (2007) - $150 Million to make/$693 Million World Wide
Now, I offer to let You do the math.
How in the world some of You guys are saying he doesn't have a stellar success rate, is completely and utterly beyond me (and it would seem, those things called facts), because out of every movie the man has thus far made, he's only made ONE MOVIE that didn't make near or (more commonly more then) double the production costs of the film. I don't know what world You people are living in, and Your more then welcome to Your personal opinions as to whether his films are "good" or "bad" (personally, I thought Transformers was ridiculously stupid myself, as the plot holes were so big Unicron could fly through them), but to say the man isn't a successful filmmaker when he has those confirmed numbers saying quite loudly that he is, is well, just plain stupid and uneducated.
Hell, the island is a crappy movie, I'll give You guys that, but it wasn't a horrible train wreck as everyone makes it out to me. It was just below making double what it cost to produce. It wasn't a success domestically in the U.S. for sure, but in Hollywood, all they care about is if it makes a profit. And it assuredly managed to pull that off, being the stinker it was.
