Some of the worst reviews I've read was on EGM. The reviewers were bunch of Microsoft Xbox 360/Halo fanboys. I remember they were hesitant to give Call of Duty 4: Modern Warfare high reviews because it wasn't Halo. They also expressed their hate towards the PS3 at the time (2007 to 2008) so any PS3 title gets a negative review from them.
IGN also had some horrible fanboy reviews, notable Halo 4. Fanboy much review right there.
"Once you've received your new special friend, you'll want to help him be the best he can be. To do this, you'll need to send him to ranked tournaments, which will help him level up his class. Instead of battling until your monster drops like you do in Pokemon, every fight is limited to one minute. You can either control the battle or let your monster fend for itself -- there doesn't seem to be an advantage either way."
Obviously has no clue how the battle system works, Monster Rancher DS's battle system is actually very exploitable, to the fact that you can win pretty much every battle even if you're seriously outclassed by your opponent by abusing defense panels.
