Meh I don't think so. JLC has been in many big movies and has been brilliant. Early Halloween movies, Trading Places etc.
They are all proven actors. You can't blame them really for a badly written movie.
I watched Penguinz talking about it and he got it spot on. Borderlands 1&2 were brilliant. 3? just wasn't funny at all, and neither was the pre sequel.
Tiny Tina's Wonderlands was the best since 2. It was genuinely funny at times (especially the Murphs). But yeah, comedy wise it has lost its way IMO.
