My thoughts!
Episode 42:
I really shouldn't have read some comments before seeing the episode. A lot of people were praising it as the episode they've been wanting to see, but really the whole episode was just a major boss battle. There was teamwork between the two teams, but that's hardly what I wanted to see in this show.
Episode 43:
But THIS episode is more like what I had in mind! Noel possibly being a double (or should I say, triple) agent for both the Rangers and the Ganglers?! Why didn't we get to this sooner?! I totally predicted something like this would happen way back at the start of the show!
Episode 44:
...And then this episode killed all that potential off. That ending was so weak. I guess it was kind of predictable that the old cop buddy from out of town was a Gangler in disguise, but I wish they hadn't gone the predictable route. What's even more lame is how there were two races of Ganglers, one that looked human but got outrun by the monstrous Ganglers. Isn't it kind of late to be falling back on Sentai cliches like this? So much story potential wasted...
Episode 45:
Well, I'll admit, the Mortal Kombat reference surprised me. Not saying it was a well placed reference, but it surprised me. Speaking of out of place, was there something I'm missing? Was salmon previously a traditional meal around Christmas time for Japan, or is this show just spouting random nonsense to be funny? Also, not sure why I didn't notice this sooner, but I like how the different Super forms are handled! Lupin Red's super form really reflects the all-for-one ideology of the LupinRangers, but Lupin X's golden super mode encourages teamwork with those handles/triggers on the side that can be used by other PatRangers. (Which is why I would have preferred Patren X getting a super form instead, since the same gimmick could also be used by the Lupin Rangers. Or maybe a super form for Patren #1 to balance things out. Just a thought.) And of course Keiichiro would be the first to figure out who the LupinRangers are. Why not?
Episode 46:
I normally don't mind a clip show, as long as it tries to throw in SOME story, or do something to expand on previous events with new details. This show... Sort of did the former? Keiichiro brought everyone up to speed on who the LupinRangers are, so now they have a plan. And honestly, I wish they hadn't killed off this villain so fast. His design was lame, but he could have been cool! Even though his plan to steal the pieces of the Lupin Collection failed, he still could have used that power to gather intel on the LupinRangers/PatRangers. Or just keep them in that pocket dimension forever. That could have lead to a potentially good story ending with the LupinRangers' identities being exposed once and for all. But again, wasted potential.
