Though Forster attempts to build excitement through each project's many steps, some episodes are less interesting than others. For example, one that detailed an extremely complicated Swedish project called the Hallandsas Ridge Tunnel is dull despite the narrator's enthusiasm and the pre-commercial break cliffhangers (what will happen after the dynamite blast to that wall?!). The episodes that deal with issues that are more familiar to viewers -- like the one exploring the Big Dig -- are more attention-grabbing. So kids with a particular interest in engineering, construction, science, and math may well find Extreme Engineering fascinating, but others probably won't be converted.
