Hehe, somehow I had a feeling we'd be in the minority.
The reasons for the comparisons are very clear, and I don't disagree with others on that.
However, it's worth questioning the integrity of the reviewer if indeed they're more concerned with making "an effort to elevate the new IP and hopefully garner more attention/sales."
If a review site is referencing another game in order to elevate a new IP/sales, then surely that's representative of bias, and suggests they aren't able to look at a game objectively on its own merits.
On the other hand, if they're referencing another game in order to garner attention (to themselves)...well, that just comes across as unprofessional.
If you absolutely must compare, I'm inclined to say it'd make more sense to have a clear "Peer Comparison" list (or use YouTube to document a video on the differences, like many people do already).
But in the review body itself, it's a blatant cop-out, and creates a vicious cycle as gamers expect comparisons to be made, because that's the only way they feel able to understand how a game plays (when in fact it only reinforces a superficial understanding).
Sorry everyone for this turning into a rant. I probably have enough to say about modern reviews to make a thread, but that's probably been done a hundred times already...
