idk, maybe you're a diff generation (35-45?) but I think the CG is a cool touch.
Do you know how hard CG actually is? If anything, CG is harder than stop motion--and stop motion is very hard to pull off well.
Using CG/FMV to create a video clip of something truly life-like is impressive. Think Blizzard/SWTOR video clips.
Using actual lego pieces to create a world and making a video using those real pieces is impressive because it takes time to build w/ legos.
However, using a computer to create a lego video just seems like cheating. You're not doing any of the hard work (putting legos together)...the computer is. CG videos are hard when you try to create something life-like. A CG video of lego pieces is, imo, a lot easier since it lacks the detail you would see in a good CG video.
Also, CG videos like blizzard's and SWTOR cost well into the hundreds of millions. I highly doubt that the lego one you linked cost that much and probably wasn't anywhere nearly as difficult to create as a blizzard/swtor cg.
It's for those reasons I felt the lego clip was lackluster at best and resembled a silly saturday morning cartoon for kids.
