Eeh, I didn't mind most of the western comic tributes, but the how much the guy looked like Venom was just a bit much to handle. The same goes for Tomoe and Rei, which is one of the main reasons why I preferred the OVA to that part of the mango. I would have been fine with it had Rurouni Kenshin been a parody series, but it's not.
At least Jin-e was dissimilar enough in terms of appearance to separate from Gambit. THAT'S a tribute done right.
