That hisnagdus saved chassidus and thus everything he says is pasul
Lol, just say you have no clue

. (Can generally serve you well)
Happens to be that point is not the one I necessarily disagree with... It's his weird and fantasy pirushim on the Parsha,-famously on the Maakos, on minhagim, he loves to find "mistakes" on what the rishonim wrote and plagiarizes other's chidushim as well. Rav Aaron said that the good thing about his chumash is when you skip a page by mistake it's nothing to cry over. (which is somewhat interesting, because his style and issues put aside, he still did a phenomenal work in Torah Temima, given the genius he was.)
