Peter Ericson’s review published on Letterboxd :
Amusing rather than laugh-out-loud funny, "Ice Age: Dawn of the Dinosaurs" finds a good balance between kid-oriented and adult-oriented humor and themes, but it is too bland and slightly too long to be consistently engaging.
The characters are imbued with individuality, although they are not fully fleshed out. While Sid may come across as annoying at first—I initially thought I would dislike him throughout the movie—he is actually the most sympathetic character in the film.
Most of the sequences featuring Scrat, Scratte, and the acorn are hilarious; however, the excellent lonely-acorn sequence stands out not for being funny but for being surprisingly emotional.
The animation is solid without being memorable.
Satisfying, if unremarkable, voice work from Robert Gustafsson (Sid), Björn Granath (Manny), Reine Brynolfsson (Diego), Eva Röse (Ellie), and Claes Malmberg (Buck). I saw the Swedish-dubbed version of the film not by choice but because it was, and still is, the only version playing at “my” theater.
