Iron Man 2

"Rourke and Rockwell make satisfying, complementary villains, while Downey Jr. delivers again. Shame this sequel feels inessential, over-busy and a little, well, mechanical. Nothing they can’t put right for Iron Man 3. (...) Rating: ★★★ (out of five)" 

All told, "Iron Man 2" suffers the same fate as many a sequel. Where the first film felt buoyant and occasionally inspired in helpfully (...) the new pic feels more duty-bound and industrial" 

"Everything fun and terrific about 'Iron Man,' (...) has vanished with its sequel. In its place, 'Iron Man 2' has substituted noise, confusion, multiple villains, irrelevant stunts and misguided story lines." 

"The good news is that Iron Man is back. The bad news is that he brought lots of company (...) The movie strains under the weight of an excessively crammed story. Heroes and villains are shoehorned in" 

"Downey is actually better (...) than ever, even when the movie buries him in unnecessary clutter. Too many stunts, too many subplots, too many villains jammed in from the Marvel Comics universe, too many romping, stomping, clanking iron armies (...) Rating: ★★★(out of four)" 

"A polished, high-ozone sequel, not as good as the original but building once again on a quirky performance by Robert Downey Jr. (...) Rating: ★★★ (out of four)"
