Harry Potter and the Half-Blood Prince
*** 1/2 ( 3 1/2 STARS)
$ 158 million
Running time: 153 minutes
What it's about: Harry Potter (Daniel Radcliffe, above) must persuade an eccentric potions professor to reveal one source of Voldemort's power.
Our take: As Harry enters the thick of adolescence, the filmmakers reward him with a movie that bubbles and pops with humor and feeling.
Ice Age: Dawn of the Dinosaurs
** ( 2 STARS)
Running time: 94 minutes
What it's about: The joys and panics of impending parenthood for woolly mammoths inspire Sid the sloth (above) to adopt three dinosaur babies.
Our take: Simon Pegg's weasel adds pizazz, but the regular characters are all used up, and the 3-D makes you feel as if you're caught between the strings of a ukulele.
Transformers: Revenge of the Fallen
* ( 1 STAR)
Running time: 137 minutes
What it's about: The good-guy robot aliens, the Autobots, team up with a gutsy U.S. military unit - and Megan Fox and Shia LaBeouf - to bring down the bad-guy robot aliens, the Decepticons.
Our take: The whirl, bang and general bother of crashing gears and gnashing metals end up suffocating the senses.
* 1/2 ( 1 1/2 STARS)
Running time: 81 minutes
What it's about: Sacha Baron Cohen's gay fashionista Bruno leaves Austria for Los Angeles, hoping to become a towering international celebrity.
Our take: Yesterday's emperor of movie comedy truly has no clothes. For a portrait of a monomaniac, it's alarmingly random; for an expose of charlatans, it's maddeningly shoddy.
* ( 1 STAR)
Running time: 107 minutes
What it's about: Sandra Bullock (above), a high-powered, Canadian-born book editor, discovers that she must marry her Alaskan-born assistant (Ryan Reynolds) or be deported.
Our take: The movie never gives any reason to buy the conceit that these two careerists grow to share love.
