While far from perfect, (short final battles), I think that Bob is far too harsh on the Iron Man series. They're good films. Actually, they're great films.
I can't see Pacific Rim doing much more than break even. Giant robots fight aliens? That's niche, and even the mainstream Transformers movies only really made money from super fanboys at first, and subsequently the kids who liked the toys. Plus, it's hard to suspend disbelief about giant robots in an apocalyptic future. The only genre that can pull it off is anime, because they mix in a ton of politics, and have a far longer running time to explain themselves. Sorry, but I can't see it being any good, regardless of who directs it.
And Warner Bros strikes again with Superman. I can almost see the board meeting now: "Batman was dark and successful. Green Lantern was bright and flopped. Let's make Superman even darker, and get that chappy who worked on Batman to help out". There seems to be little and less regard for the source material, which is a shame - you'll notice that each of the Marvel Studios films have been catered to the character and original books to almost insane lengths... and the proof is in the pudding. Man of Steel trailer is terrible, and while that doesn't write it off as a film, it certainly is a bad start.
