Ooooh! Plenty! I think that many mainstream classics are a bunch of old tosh - american beauty? Schindler's List? Contact? Phooey I Say!
Latest example of review overkill is LOTR III. The editing is truly awful. Just because you decide to over-use 'Slo-mo' doesn't make the film great! The pacing, as a result, is dire IMHO.
I think that there are many films that reviewers say are rubbish but I like - you tend to find that a particular piece of media will gear their reviews to their target audience (eg Max Power may adore 2Fast2Furious whilst Needlework Monthly hates it).
It's just the way that it is.
I really liked Final Destination 2 for instance. I thought that it was witty, clever and 'going for broke' with the death sequences rather than replicating the original and creating yet another teen/slasher combo. Others disagreed...
