Hmm, the problem with this question is that you're never really going to get a straight answer. There will be many who come in and bash on the newer seasons while there will be some who actually give a thumbs up to the anime today. Those who dislike it is probably because they are strong believers in that the original anime was the best and that today's Pokémon show has become old, horrible, and predictable. Those who say they like it, is probably because they've given it a chance and has grown to enjoy it or because they like Pokémon in general and aren't hard criticizers of the show today, but watch it just for entertainment.
Me, I like the Pokémon anime that runs today for the DP arc. It's enjoyable and maybe it might not be the best like it used to be, but I watch it for the same reason I watched it before, because it interests me. I would suggest that you probably take some time and watch the newer series and judge on your own whether you like it or not. If you do, then hey, try and find the past newer shows you missed and try to pick up from where you left off. If not, then it's probably best you don't waste your time watching the show, but continue playing the games if that's what you prefer.
