Should critics be sued for giving good reviews to a bad film

Got cheap a few days ago. Not watched but came to see what may be online about it. Back cover is littered with abut 20 award balloon blurbs. and displays what seem to be positive critic or journalist [type] acclaims. How can the few who have commented be so opposite to those mentioned?

Would not like those type of judges [bought maybe] to be involved in judge scoring sports. Mind you if winning something is down to an opinion it is my opinion that it is not a fully competitive sport. That is why boxers need to put someones lights out to be sure they have won. Sorry. Deviation.
