OK, so the CGI was pretty decent, and the Hitchhiker's reference was nice, but the rest...
First, this is not the opening scene, so the title above should be fixed. And the position of the "ish" seems to refer to Lego, which is still sorta true seeing as this is 75% CGI. And what's the point of commenting 34 times on your own video? People can see who commented, and seeing the same person over and over doesn't look good at all. Not sure what you're trying to gain by doing that.
The point of R2 is that the surrounding character's phrases give a sense of what he said. The subtitles threw me off, and weren't necessary. The interior set changes with almost every shot. There's no continuity in those few "real" shots. The animation is decent, but doesn't match with the voices, and the set bumping isn't consistent. (This is one time where it's fine, but it would bounce around, and then not, and then a bit.)
To conclude, it's mis-marketed, and while the CGI is good, there's little else to appeal to viewers.
