Several would feel that way, Various reasons
1) Voice acting (seiyuu) in Japan is a semi respectable trade, outside it and with the exception of a handful of European countries (Germany, France and Italy in varying degrees do it well) it tends to be a mix of random actor actor that is slumming it one day or some they rounded up down the local community theatre, especially if you are doing a cheap anime DVD or worse still a game. Bonus points if you are trying to find English speaking actors in Japan to dub in Japan from the get go.
2) Most games and anime are not high art. Presumably you don't understand Japanese so when the usually grade school writing and cringeworthy dialogue comes on you don't inherently understand it and can treat it a bit like some music or something.
3) Check to see what the dubs are mastered in --> your glorious 5.1 DTS Japanese track is likely not going to compete with 2 channel minimal bitrate AC3 that the dub often sports, and recorded in the kind of place that you hire when you are using actors you found in the community theatre.
4) To go with 1) and with the exception of those European countries it is not going to be rewritten that well to match timing in the shows, and most shows will not match timing to the English dub. Japanese in speech is not that much different to English in length to convey a point like it can be for the written side of things but it is not exactly the same all the time either. Also going by some stories from said community theatre types then it is often a factory process and might lack table reads, the option for the actors to go through the script and also do enough takes to get it done properly.
5) You are a filthy weab. It is an unfortunate affliction, you can often cure it by going to Japan and seeing that it is not all sunshine and rainbows (best not to go during the sunshine and rainbows festival) or you can finish going through puberty instead.
