Jim Belushi isn't seeing eye-to-eye with his "Thunderstruck" co-star Kevin Durant -- telling TMZ Sports it was a GOOD MOVIE ... despite the fact KD recently dissed the flick.
In fact, KD hated the 2012 movie so much ... he told us he thought "Kazaam" was better and swore off acting forever.
For the record, "Thunderstruck" was considered a box-office disaster ... raking in less than $600k in the U.S.
But last night in L.A., Belushi defended "Thunderstuck" -- and hailed Durant as a "stud."
There's just one thing ... check out Belushi's reaction when we asked if he thought KD should keep acting. He doesn't exactly say "yes."
