Studies have shown it's effective. I have seen it's effects on someone close to me. Rather spectacular, and yet not a full "cure". I was inspired enough to try it and had limited success. It doesn't work for everyone or everything. PTSD it's definitely worth giving a shot.

From what I can find you’re right, sort of. The “sort of” is summarized here:

So, now to the bottom line: EMDR ameliorates symptoms of traumatic anxiety better than doing nothing and probably better than talking to a supportive listener. Yet not a shred of good evidence exists that EMDR is superior to exposure-based treatments that behavior and cognitive-behavior therapists have been administering routinely for decades. Paraphrasing British writer and critic Samuel Johnson, Harvard University psychologist Richard McNally nicely summed up the case for EMDR: “What is effective in EMDR is not new, and what is new is not effective.”

Studies have shown that the studies you reference have a reproduce-result of only 39 %.

Please name the concrete study and whether it could be reproduced.

Did a few sessions back in the 90s, utterly useless, IME. Probably depends on entirely on the subject, for some it may be a miracle therapy.

At the very least it's a profitable venture for the therapist, well north of $100 per session, IIRC.
