Commercials can sometimes be mildly entertaining, or even fun to watch (think big budget ads like during the Superbowl). They can be somewhat informative, show me an interesting product I wasn't aware of, and make me go out and research it more from other sources.
I think of "reviewers" like Huff in that same exact way. I won't specifically seek them out, but sometimes I come across them when they feature new things that I haven't seen before. If the new thing looks intriguing I will read up on it from more reliable sources.
Steve seems like a nice guy but he does love pretty much everything. So not very useful as a critic. Having him discuss the features of a product can be useful but that's about it. Also his ghost hunting stuff is not my cup of tea and confirms to me that he isn't the type of person I find reliable.
