There is one decent joke, or at least there would be if it wasn't so often repeated, that Strange, Namor and Dormammu sound like idiots with their constant grandstanding and verbose soliloquies. Yes, it's funny, the first three times, but then it grates. Rule of threes people. Although the original Defenders line-up is fun to see and evokes the Silver Age, Indefensible is probably closest to the old "Not Brand ECHHS" stuff in terms of tone. I get that these characters are, by their very nature, over the top in how they are presented, I feel that a whole limited series was far more than needed to get this joke across. I suppose that Indefensible is at least better than Secret Defenders.
Not much to say on this one, it's not that good and the jokes tend to fall flat pretty quick. It doesn't have the wry humour of Marvel NOW! Hawkeye or the non-sequitur irreverence of Next Wave. I'm usually keen for any amount of Namor, but the one presented here is a pastiche of the character rather than a solid representation of what he's like in contermporary Marvel comics.
